For Lie groups, the `exponential map` above is the most obvious mapping: it
associates straight lines in the tangent space with geodesics on the manifold
(and it's inverse, the log map). However, there are two cases in which we deviate from this:
(and it's inverse, the log map). However, there are several cases in which we deviate from this:
However, the exponential map is unnecessarily expensive for use in optimization. Hence, in GTSAM there is the option to provide a cheaper chart by means of the `ChartAtOrigin` struct in a class. This is done for *SE(2)*, *SO(3)* and *SE(3)* (see `Pose2`, `Rot3`, `Pose3`)
Most Lie groups we care about are *Matrix groups*, continuous sub-groups of *GL(n)*, the group of *n x n* invertible matrices. In this case, a lot of the derivatives calculations needed can be standardized, and this is done by the `LieGroup` superclass. You only need to provide an `AdjointMap` method.
A CRTP helper class `LieGroup` is available that can take a class and create some of the Lie group methods automatically. The class needs:
* operator* : implements group operator
* inverse: implements group inverse
* AdjointMap: maps tangent vectors according to group element
* Expmap/Logmap: exponential map and its inverse
* ChartAtOrigin: struct where you define Retract/Local at origin
To use, simply derive, but also say `using LieGroup<Class,N>::inverse` so you get an inverse with a derivative.
Finally, to create the traits automatically you can use `internal::LieGroupTraits<Class>`

Important Installation Notes
----------------------------
1)
GTSAM requires the following libraries to be installed on your system:
- BOOST version 1.43 or greater (install through Linux repositories or MacPorts)
- Cmake version 2.6 or higher
- Support for XCode 4.3 command line tools on Mac requires CMake 2.8.8 or higher
Optional dependent libraries:
- If TBB is installed and detectable by CMake GTSAM will use it automatically.
Ensure that CMake prints "Use Intel TBB : Yes". To disable the use of TBB,
disable the CMake flag GTSAM_WITH_TBB (enabled by default). On Ubuntu, TBB
may be installed from the Ubuntu repositories, and for other platforms it
may be downloaded from https://www.threadingbuildingblocks.org/
Tested compilers:
- GCC 4.2-4.7
- OSX Clang 2.9-5.0
- OSX GCC 4.2
- MSVC 2010, 2012
Tested systems:
- Ubuntu 11.04 - 13.10
- MacOS 10.6 - 10.9
- Windows 7, 8, 8.1
Known issues:
- MSVC 2013 is not yet supported because it cannot build the serialization module
of Boost 1.55 (or earlier).

GTSAM makes extensive use of debug assertions, and we highly recommend you work
in Debug mode while developing (enabled by default). Likewise, it is imperative
that you switch to release mode when running finished code and for timing. GTSAM
will run up to 10x faster in Release mode! See the end of this document for
additional debugging tips.
3)
GTSAM has Doxygen documentation. To generate, run 'make doc' from your
build directory.
4)
The instructions below install the library to the default system install path and
build all components. From a terminal, starting in the root library folder,
execute commands as follows for an out-of-source build:
$] mkdir build
$] cd build
$] cmake ..
$] make check (optional, runs unit tests)
$] make install
This will build the library and unit tests, run all of the unit tests,
and then install the library itself.
- CMake Configuration Options and Details
GTSAM has a number of options that can be configured, which is best done with
one of the following:
ccmake the curses GUI for cmake
cmake-gui a real GUI for cmake
Important Options:
CMAKE_BUILD_TYPE: We support several build configurations for GTSAM (case insensitive)
Debug (default) All error checking options on, no optimization. Use for development.
Release Optimizations turned on, no debug symbols.
Timing Adds ENABLE_TIMING flag to provide statistics on operation
Profiling Standard configuration for use during profiling
RelWithDebInfo Same as Release, but with the -g flag for debug symbols
CMAKE_INSTALL_PREFIX: The install folder. The default is typically /usr/local/
To configure to install to your home directory, you could execute:
$] cmake -DCMAKE_INSTALL_PREFIX:PATH=$HOME ..
GTSAM_TOOLBOX_INSTALL_PATH: The Matlab toolbox will be installed in a subdirectory
of this folder, called 'gtsam'.
$] cmake -DGTSAM_TOOLBOX_INSTALL_PATH:PATH=$HOME/toolbox ..
GTSAM_BUILD_CONVENIENCE_LIBRARIES: This is a build option to allow for tests in
subfolders to be linked against convenience libraries rather than the full libgtsam.
Set with the command line as follows:
$] cmake -DGTSAM_BUILD_CONVENIENCE_LIBRARIES:OPTION=ON ..
ON (Default) This builds convenience libraries and links tests against them. This
option is suggested for gtsam developers, as it is possible to build
and run tests without first building the rest of the library, and
speeds up compilation for a single test. The downside of this option
is that it will build the entire library again to build the full
libgtsam library, so build/install will be slower.
OFF This will build all of libgtsam before any of the tests, and then
link all of the tests at once. This option is best for users of GTSAM,
as it avoids rebuilding the entirety of gtsam an extra time.
GTSAM_BUILD_UNSTABLE: Enable build and install for libgtsam_unstable library.
Set with the command line as follows:
$] cmake -DGTSAM_BUILD_UNSTABLE:OPTION=ON ..
ON When enabled, libgtsam_unstable will be built and installed with the
same options as libgtsam. In addition, if tests are enabled, the
unit tests will be built as well. The Matlab toolbox will also
be generated if the matlab toolbox is enabled, installing into a
folder called "gtsam_unstable".
OFF (Default) If disabled, no gtsam_unstable code will be included in build or install.
Check
"make check" will build and run all of the tests. Note that the tests will only be
built when using the "check" targets, to prevent "make install" from building the tests
unnecessarily. You can also run "make timing" to build all of the timing scripts.
To run check on a particular module only, run "make check.[subfolder]", so to run
just the geometry tests, run "make check.geometry". Individual tests can be run by
appending ".run" to the name of the test, for example, to run testMatrix, run
"make testMatrix.run".
MEX_COMMAND: Path to the mex compiler. Defaults to assume the path is included in your
shell's PATH environment variable. mex is installed with matlab at
$MATLABROOT/bin/mex
$MATLABROOT can be found by executing the command 'matlabroot' in MATLAB
Debugging tips:
Another useful debugging symbol is _GLIBCXX_DEBUG, which enables debug checks
and safe containers in the standard C++ library and makes problems much easier
to find.
NOTE: The native Snow Leopard g++ compiler/library contains a bug that makes
it impossible to use _GLIBCXX_DEBUG. MacPorts g++ compilers do work with it though.
NOTE: If _GLIBCXX_DEBUG is used to compile gtsam, anything that links against
gtsam will need to be compiled with _GLIBCXX_DEBUG as well, due to the use of
header-only Eigen.

# Quickstart
In the root library folder execute:
```sh
$ mkdir build
$ cd build
$ cmake ..
$ make check # (optional, runs unit tests)
$ make install
```
## Important Installation Notes
1. GTSAM requires the following libraries to be installed on your system:
- BOOST version 1.43 or greater (install through Linux repositories or MacPorts)
- Cmake version 3.0 or higher
- Support for XCode 4.3 command line tools on Mac requires CMake 2.8.8 or higher
Optional dependent libraries:
- If TBB is installed and detectable by CMake GTSAM will use it automatically.
Ensure that CMake prints "Use Intel TBB : Yes". To disable the use of TBB,
disable the CMake flag GTSAM_WITH_TBB (enabled by default). On Ubuntu, TBB
may be installed from the Ubuntu repositories, and for other platforms it
may be downloaded from https://www.threadingbuildingblocks.org/
- GTSAM may be configured to use MKL by toggling `GTSAM_WITH_EIGEN_MKL` and
`GTSAM_WITH_EIGEN_MKL_OPENMP` to `ON`; however, best performance is usually
achieved with MKL disabled. We therefore advise you to benchmark your problem
before using MKL.
Tested compilers:
- GCC 4.2-7.3
- OS X Clang 2.9-10.0
- OS X GCC 4.2
- MSVC 2010, 2012, 2017
Tested systems:
- Ubuntu 16.04 - 18.04
- MacOS 10.6 - 10.14
- Windows 7, 8, 8.1, 10

- MSVC 2013 is not yet supported because it cannot build the serialization module
of Boost 1.55 (or earlier).

## CMake Configuration Options and Details
GTSAM has a number of options that can be configured, which is best done with
one of the following:
- ccmake the curses GUI for cmake
- cmake-gui a real GUI for cmake
### Important Options:
#### CMAKE_BUILD_TYPE
We support several build configurations for GTSAM (case insensitive)
```cmake -DCMAKE_BUILD_TYPE=[Option] ..```
- Debug (default) All error checking options on, no optimization. Use for development.
- Release Optimizations turned on, no debug symbols.
- Timing Adds ENABLE_TIMING flag to provide statistics on operation

$MATLABROOT can be found by executing the command `matlabroot` in MATLAB
## Performance
Here are some tips to get the best possible performance out of GTSAM.
1. Build in `Release` mode. GTSAM will run up to 10x faster compared to `Debug` mode.
2. Enable TBB. On modern processors with multiple cores, this can easily speed up
optimization by 30-50%. Please note that this may not be true for very small
problems where the overhead of dispatching work to multiple threads outweighs
the benefit. We recommend that you benchmark your problem with/without TBB.
3. Add `-march=native` to `GTSAM_CMAKE_CXX_FLAGS`. A performance gain of
25-30% can be expected on modern processors. Note that this affects the portability
of your executable. It may not run when copied to another system with older/different
processor architecture.
Also note that all dependent projects *must* be compiled with the same flag, or
seg-faults and other undefined behavior may result.
4. Possibly enable MKL. Please note that our benchmarks have shown that this helps only
in very limited cases, and actually hurts performance in the usual case. We therefore
recommend that you do *not* enable MKL, unless you have benchmarked it on
your problem and have verified that it improves performance.
## Debugging tips
Another useful debugging symbol is _GLIBCXX_DEBUG, which enables debug checks and safe containers in the standard C++ library and makes problems much easier to find.
NOTE: The native Snow Leopard g++ compiler/library contains a bug that makes it impossible to use _GLIBCXX_DEBUG. MacPorts g++ compilers do work with it though.
NOTE: If _GLIBCXX_DEBUG is used to compile gtsam, anything that links against gtsam will need to be compiled with _GLIBCXX_DEBUG as well, due to the use of header-only Eigen.
## Installing MKL on Linux
Intel has a guide for installing MKL on Linux through APT repositories at <https://software.intel.com/en-us/articles/installing-intel-free-libs-and-python-apt-repo>.
After following the instructions, add the following to your `~/.bashrc` (and afterwards, open a new terminal before compiling GTSAM):
`LD_PRELOAD` need only be set if you are building the cython wrapper to use GTSAM from python.
```sh
source /opt/intel/mkl/bin/mklvars.sh intel64
export LD_PRELOAD="$LD_PRELOAD:/opt/intel/mkl/lib/intel64/libmkl_core.so:/opt/intel/mkl/lib/intel64/libmkl_sequential.so"
```
To use MKL in GTSAM pass the flag `-DGTSAM_WITH_EIGEN_MKL=ON` to cmake.
The `LD_PRELOAD` fix seems to be related to a well known problem with MKL which leads to lots of undefined symbol errors, for example:
- <https://software.intel.com/en-us/forums/intel-math-kernel-library/topic/300857>
- <https://software.intel.com/en-us/forums/intel-distribution-for-python/topic/628976>
- <https://groups.google.com/a/continuum.io/forum/#!topic/anaconda/J3YGoef64z8>
Failing to specify `LD_PRELOAD` may lead to errors such as:
`ImportError: /opt/intel/mkl/lib/intel64/libmkl_vml_avx2.so: undefined symbol: mkl_serv_getenv`
or
`Intel MKL FATAL ERROR: Cannot load libmkl_avx2.so or libmkl_def.so.`
when importing GTSAM using the cython wrapper in python.

GTSAM is a C++ library that implements smoothing and
mapping (SAM) in robotics and vision, using Factor Graphs and Bayes
Networks as the underlying computing paradigm rather than sparse
matrices.
On top of the C++ library, GTSAM includes a MATLAB interface (enable
GTSAM_INSTALL_MATLAB_TOOLBOX in CMake to build it). A Python interface
is under development.

GTSAM 4 Compatibility
---------------------
## GTSAM 4 Compatibility
GTSAM 4 will introduce several new features, most notably Expressions and a python toolbox. We will also deprecate some legacy functionality and wrongly named methods, but by default the flag GTSAM_ALLOW_DEPRECATED_SINCE_V4 is enabled, allowing anyone to just pull V4 and compile. To build the python toolbox, however, you will have to explicitly disable that flag.

To build the python toolbox, however, you will have to explicitly disable that flag.
Also, GTSAM 4 introduces traits, a C++ technique that allows optimizing with non-GTSAM types. That opens the door to retiring geometric types such as Point2 and Point3 to pure Eigen types, which we will also do. A significant change which will not trigger a compile error is that zero-initializing of Point2 and Point3 will be deprecated, so please be aware that this might render functions using their default constructor incorrect.

The Preintegrated IMU Factor
----------------------------
## Wrappers
We provide support for [MATLAB](matlab/README.md) and [Python](cython/README.md) wrappers for GTSAM. Please refer to the linked documents for more details.
## The Preintegrated IMU Factor
GTSAM includes a state of the art IMU handling scheme based on

If you are using the factor in academic work, please cite the publications above.
In GTSAM 4 a new and more efficient implementation, based on integrating on the NavState tangent space and detailed in docs/ImuFactor.pdf, is enabled by default. To switch to the RSS 2015 version, set the flag **GTSAM_TANGENT_PREINTEGRATION** to OFF.

Compiling/Linking with gtsam:
The installation creates a binary "libgtsam" at the installation prefix,
and an include folder "gtsam". These are the only required includes, but
the library has also been designed to make use of XML serialization through
the Boost.serialization library, which requires the the Boost.serialization
headers and binaries to be linked.
If you use CMake for your project, you can use the CMake scripts in the
cmake folder for finding GTSAM, CppUnitLite, and Wrap.

# Using GTSAM_EXPORT
To create a DLL in windows, the `GTSAM_EXPORT` keyword has been created and needs to be applied to different methods and classes in the code to expose this code outside of the DLL. However, there are several intricacies that make this more difficult than it sounds. In general, if you follow the following three rules, GTSAM_EXPORT should work properly. The rest of the document also describes (1) the common error message encountered when you are not following these rules and (2) the reasoning behind these usage rules.
## Usage Rules
1. Put `GTSAM_EXPORT` in front of any function that you want exported in the DLL _if and only if_ that function is declared in a .cpp file, not just a .h file.
2. Use `GTSAM_EXPORT` in a class definition (i.e. `class GSTAM_EXPORT MyClass {...}`) only if:
* At least one of the functions inside that class is declared in a .cpp file and not just the .h file.
* You can `GTSAM_EXPORT` any class it inherits from as well. (Note that this implictly requires the class does not derive from a "header-only" class. Note that Eigen is a "header-only" library, so if your class derives from Eigen, _do not_ use `GTSAM_EXPORT` in the class definition!)
3. If you have defined a class using `GTSAM_EXPORT`, do not use `GTSAM_EXPORT` in any of its individual function declarations. (Note that you _can_ put `GTSAM_EXPORT` in the definition of individual functions within a class as long as you don't put `GTSAM_EXPORT` in the class definition.)
## When is GTSAM_EXPORT being used incorrectly
Unfortunately, using `GTSAM_EXPORT` incorrectly often does not cause a compiler or linker error in the library that is being compiled, but only when you try to use that DLL in a different library. For example, an error in gtsam/base will often show up when compiling the check_base_program or the MATLAB wrapper, but not when compiling/linking gtsam itself. The most common errors will say something like:
```
Error LNK2019 unresolved external symbol "public: void __cdecl gtsam::SO3::print(class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> > const &)const " (?print@SO3@gtsam@@QEBAXAEBV?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@@Z) referenced in function "public: static void __cdecl gtsam::Testable<class gtsam::SO3>::Print(class gtsam::SO3 const &,class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> > const &)" (?Print@?$Testable@VSO3@gtsam@@@gtsam@@SAXAEBVSO3@2@AEBV?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@@Z) check_geometry_program C:\AFIT\lib\gtsam\build\gtsam\geometry\tests\testSO3.obj
```
Let's analyze this error statement. First, there is an unresolved symbol `gtsam::SO3::print`. This can occur because _either_ `GTSAM_EXPORT` was not added to the print function definition when it should have been, _OR_ because `GTSAM_EXPORT` was added to the print function definition when it is fully declared in the header. This error was detected while compiling `check_geometry_program` and pulling in `...\testSO3.obj`. Specifically, within the function call `gtsam::Testable<class gtsam::SO3>::Print (...)`. Note that this error did _not_ occur when compiling the library that actually has SO3 inside of it.
## But Why?
I believe that how the compiler/linker interacts with GTSAM_EXPORT can be explained by understanding the rules that MSVC operates under.
But first, we need to understand exactly what `GTSAM_EXPORT` is. `GTSAM_EXPORT` is a `#define` macro that is created by CMAKE when GTSAM is being compiled on a Windows machine. Inside the GTSAM project, GTSAM export will be set to a "dllexport" command. A "dllexport" command tells the compiler that this function should go into the DLL and be visible externally. In any other library, `GTSAM_EXPORT` will be set to a "dllimport" command, telling the linker it should find this function in a DLL somewhere. This leads to the first rule the compiler uses. (Note that I say "compiler rules" when the rules may actually be in the linker, but I am conflating the two terms here when I speak of the "compiler rules".)
***Compiler Rule #1*** If a `dllimport` command is used in defining a function or class, that function or class _must_ be found in a DLL.
Rule #1 doesn't seem very bad, until you combine it with rule #2
***Compiler Rule #2*** Anything declared in a header file is not included in a DLL.
When these two rules are combined, you get some very confusing results. For example, a class which is completely defined in a header (e.g. LieMatrix) cannot use `GTSAM_EXPORT` in its definition. If LieMatrix is defined with `GTSAM_EXPORT`, then the compiler _must_ find LieMatrix in a DLL. Because LieMatrix is a header-only class, however, it can't find it, leading to a very confusing "I can't find this symbol" type of error. Note that the linker says it can't find the symbol even though the compiler found the header file that completely defines the class.
Also note that when a class that you want to export inherits from another class that is not exportable, this can cause significant issues. According to this [MSVC Warning page](https://docs.microsoft.com/en-us/cpp/error-messages/compiler-warnings/compiler-warning-level-2-c4275?view=vs-2019), it may not strictly be a rule, but we have seen several linker errors when a class that is defined with `GTSAM_EXPORT` extended an Eigen class. In general, it appears that any inheritance of non-exportable class by an exportable class is a bad idea.
## Conclusion
Hopefully, this little document clarifies when `GTSAM_EXPORT` should and should not be used whenever future GTSAM code is being written. Following the usage rules above, we have been able to get all of the libraries, together with their test and wrapping libraries, to compile/link successfully.

/**
* A simple 2D pose slam example
* - The robot moves in a 2 meter square
* - The robot moves 2 meters each step, turning 90 degrees after each step
* - The robot initially faces along the X axis (horizontal, to the right in 2D)
* - We have full odometry between pose
* - We have a loop closure constraint when the robot returns to the first position
*/
// In planar SLAM example we use Pose2 variables (x, y, theta) to represent the robot poses
#include <gtsam/geometry/Pose2.h>
// We will use simple integer Keys to refer to the robot poses.
#include <gtsam/inference/Key.h>
// In GTSAM, measurement functions are represented as 'factors'. Several common factors
// have been provided with the library for solving robotics/SLAM/Bundle Adjustment problems.
// Here we will use Between factors for the relative motion described by odometry measurements.
// We will also use a Between Factor to encode the loop closure constraint
// Also, we will initialize the robot at the origin using a Prior factor.
#include <gtsam/slam/BetweenFactor.h>
// When the factors are created, we will add them to a Factor Graph. As the factors we are using
// are nonlinear factors, we will need a Nonlinear Factor Graph.
#include <gtsam/nonlinear/NonlinearFactorGraph.h>
// Finally, once all of the factors have been added to our factor graph, we will want to
// solve/optimize to graph to find the best (Maximum A Posteriori) set of variable values.
// GTSAM includes several nonlinear optimizers to perform this step. Here we will use the
// a Gauss-Newton solver
#include <gtsam/nonlinear/GaussNewtonOptimizer.h>
// Once the optimized values have been calculated, we can also calculate the marginal covariance
// of desired variables
#include <gtsam/nonlinear/Marginals.h>
// The nonlinear solvers within GTSAM are iterative solvers, meaning they linearize the
// nonlinear functions around an initial linearization point, then solve the linear system
// to update the linearization point. This happens repeatedly until the solver converges
// to a consistent set of variable values. This requires us to specify an initial guess
// for each variable, held in a Values container.
#include <gtsam/nonlinear/Values.h>
using namespace std;
using namespace gtsam;
int main(int argc, char** argv) {
// 1. Create a factor graph container and add factors to it

// A prior factor consists of a mean and a noise model (covariance matrix)

graph.addPrior(1, Pose2(0, 0, 0), priorNoise);
// For simplicity, we will use the same noise model for odometry and loop closures
noiseModel::Diagonal::shared_ptr model = noiseModel::Diagonal::Sigmas(Vector3(0.2, 0.2, 0.1));
// 2b. Add odometry factors
// Create odometry (Between) factors between consecutive poses

graph.emplace_shared<BetweenFactor<Pose2> >(4, 5, Pose2(2, 0, M_PI_2), model);
// 2c. Add the loop closure constraint
// This factor encodes the fact that we have returned to the same pose. In real systems,
// these constraints may be identified in many ways, such as appearance-based techniques
// with camera images. We will use another Between Factor to enforce this constraint:
graph.emplace_shared<BetweenFactor<Pose2> >(5, 2, Pose2(2, 0, M_PI_2), model);
graph.print("\nFactor Graph:\n"); // print
// 3. Create the data structure to hold the initialEstimate estimate to the solution
// For illustrative purposes, these have been deliberately set to incorrect values
Values initialEstimate;
initialEstimate.insert(1, Pose2(0.5, 0.0, 0.2 ));
initialEstimate.insert(2, Pose2(2.3, 0.1, -0.2 ));

initialEstimate.insert(5, Pose2(2.1, 2.1, -M_PI_2));
initialEstimate.print("\nInitial Estimate:\n"); // print
// 4. Optimize the initial values using a Gauss-Newton nonlinear optimizer
// The optimizer accepts an optional set of configuration parameters,
// controlling things like convergence criteria, the type of linear
// system solver to use, and the amount of information displayed during
// optimization. We will set a few parameters as a demonstration.
GaussNewtonParams parameters;
// Stop iterating once the change in error between steps is less than this value
parameters.relativeErrorTol = 1e-5;

// Create the optimizer ...
GaussNewtonOptimizer optimizer(graph, initialEstimate, parameters);
// ... and optimize

# MATLAB Wrapper Example Project
This project serves as a lightweight example for demonstrating how to wrap C++ code in MATLAB using GTSAM.
## Compiling
We follow the regular build procedure inside the `example_project` directory:
```sh
mkdir build && cd build
cmake ..
make -j8
sudo make install
sudo ldconfig # ensures the shared object file generated is correctly loaded
```
## Usage
Now you can open MATLAB and add the `gtsam_toolbox` to the MATLAB path
```matlab
addpath('/usr/local/gtsam_toolbox')
```
At this point you are ready to run the example project. Starting from the `example_project` directory inside MATLAB, simply run code like regular MATLAB, e.g.
```matlab
pe = example.PrintExamples();
pe.sayHello();
pe.sayGoodbye();
```

# Python Wrapper
This is the Cython/Python wrapper around the GTSAM C++ library.
INSTALL
=======
## Install
- if you want to build the gtsam python library for a specific python version (eg 2.7), use the `-DGTSAM_PYTHON_VERSION=2.7` option when running `cmake` otherwise the default interpreter will be used.
- If the interpreter is inside an environment (such as an anaconda environment or virtualenv environment) then the environment should be active while building gtsam.
- This wrapper needs Cython(>=0.25.2), backports_abc>=0.5, and numpy. These can be installed as follows:
```bash
pip install -r <gtsam_folder>/cython/requirements.txt
```
- For compatiblity with gtsam's Eigen version, it contains its own cloned version of [Eigency](https://github.com/wouterboomsma/eigency.git),
- For compatibility with gtsam's Eigen version, it contains its own cloned version of [Eigency](https://github.com/wouterboomsma/eigency.git),
named **gtsam_eigency**, to interface between C++'s Eigen and Python's numpy.
- Build and install gtsam using cmake with GTSAM_INSTALL_CYTHON_TOOLBOX enabled.
The wrapped module will be installed to GTSAM_CYTHON_INSTALL_PATH, which is
by default: <your CMAKE_INSTALL_PREFIX>/cython
- Build and install gtsam using cmake with `GTSAM_INSTALL_CYTHON_TOOLBOX` enabled.
The wrapped module will be installed to `GTSAM_CYTHON_INSTALL_PATH`, which is
by default: `<your CMAKE_INSTALL_PREFIX>/cython`
- Modify your PYTHONPATH to include the GTSAM_CYTHON_INSTALL_PATH:
- To use the library without installing system-wide: modify your `PYTHONPATH` to include the `GTSAM_CYTHON_INSTALL_PATH`:
```bash
export PYTHONPATH=$PYTHONPATH:<GTSAM_CYTHON_INSTALL_PATH>
```
- To install system-wide: run `make install` then navigate to `GTSAM_CYTHON_INSTALL_PATH` and run `python setup.py install`
- (the same command can be used to install into a virtual environment if it is active)
- note: if you don't want gtsam to install to a system directory such as `/usr/local`, pass `-DCMAKE_INSTALL_PREFIX="./install"` to cmake to install gtsam to a subdirectory of the build directory.
- if you run `setup.py` from the build directory rather than the installation directory, the script will warn you with the message: `setup.py is being run from an unexpected location`.
Before `make install` is run, not all the components of the package have been copied across, so running `setup.py` from the build directory would result in an incomplete package.
## Unit Tests

The Cython toolbox also has a small set of unit tests located in the
test directory. To run them:

TODO
=====
☐ allow duplication of parent' functions in child classes. Not allowed for now due to conflicts in Cython.
☐ a common header for boost shared_ptr? (Or wait until everything is switched to std::shared_ptr in gtsam?)
☐ inner namespaces ==> inner packages?
☐ Wrap fixed-size Matrices/Vectors?
### TODO
- [ ] allow duplication of parent' functions in child classes. Not allowed for now due to conflicts in Cython.
- [ ] a common header for boost shared_ptr? (Or wait until everything is switched to std::shared_ptr in gtsam?)
- [ ] inner namespaces ==> inner packages?
- [ ] Wrap fixed-size Matrices/Vectors?

- what's the purpose of "virtual" ??
Installation:
☐ Prerequisite:
- Users create venv and pip install requirements before compiling
- Wrap cython script in gtsam/cython folder
☐ Install built module into venv?

These examples are almost identical to the old handwritten python wrapper
examples. However, there are just some slight name changes, for example
noiseModel.Diagonal becomes noiseModel_Diagonal etc...
Also, annoyingly, instead of gtsam.Symbol('b',0) we now need to say gtsam.symbol(ord('b'), 0))
`noiseModel.Diagonal` becomes `noiseModel_Diagonal` etc...
Also, instead of `gtsam.Symbol('b', 0)` we can simply say `gtsam.symbol_shorthand_B(0)` or `B(0)` if we use python aliasing.

Camera observations of landmarks (i.e. pixel coordinates) will be stored as Point2 (x, y).
Each variable in the system (poses and landmarks) must be identified with a unique key.
We can either use simple integer keys (1, 2, 3, ...) or symbols (X1, X2, L1).
Here we will use Symbols
In GTSAM, measurement functions are represented as 'factors'. Several common factors
have been provided with the library for solving robotics/SLAM/Bundle Adjustment problems.
Here we will use Projection factors to model the camera's landmark observations.
Also, we will initialize the robot at some location using a Prior factor.
When the factors are created, we will add them to a Factor Graph. As the factors we are using
are nonlinear factors, we will need a Nonlinear Factor Graph.
Finally, once all of the factors have been added to our factor graph, we will want to
solve/optimize to graph to find the best (Maximum A Posteriori) set of variable values.
GTSAM includes several nonlinear optimizers to perform this step. Here we will use a
trust-region method known as Powell's Degleg
The nonlinear solvers within GTSAM are iterative solvers, meaning they linearize the
nonlinear functions around an initial linearization point, then solve the linear system
to update the linearization point. This happens repeatedly until the solver converges
to a consistent set of variable values. This requires us to specify an initial guess
for each variable, held in a Values container.
