Alex Cunningham e8979dafad Renabled BLAS using ATLAS for Linux, fixed a variety of annoying warnings 2010-05-21 17:59:26 +00:00
Alex Cunningham fbbdd0be3e Fixed error calculation with NonlinearConstraints - now use Unit noisemodels in NonlinearConstraint to prevent having the error forced to infinity 2010-02-22 21:11:22 +00:00
Alex Cunningham ea3b8083b0 Fixed more tests for NonlinearConstraints, inequality constraints now work. 2010-02-07 01:18:17 +00:00
Alex Cunningham 219dfd262d SQP now works with single configs using the TupleConfigs, without needing a separate optimizer. 2010-02-06 05:14:52 +00:00
Alex Cunningham 67744a5f07 Changed NonlinearConstraint to correctly use new keys 2010-02-04 16:08:11 +00:00
Alex Cunningham 59c7ce7e29 Integrated householder-based QR into NoiseModel. Note that the examples for GFG have changed to ensure that they are actually a linearized version of the nonlinear example. 2010-01-27 04:39:35 +00:00
Frank Dellaert 351cdd18c2 case change: SharedGaussian and SharedDiagonal are now classes with their own header file. Needed for MATLAB TORO hail Mary 2010-01-22 17:36:57 +00:00
Alex Cunningham 5f588031bc Merged NoiseQR back into trunk 2010-01-20 18:32:48 +00:00
Alex Cunningham 88e465910a SQP tests and implementation now use the new Key system 2010-01-19 05:33:44 +00:00
Frank Dellaert a4a6e002e5 NOISE MODEL.
This is a big edit but with no templates involed, so it should not be a big deal.

New namespace gtsam::noiseModel collects all noise models, which provide efficient whitening and chain-rule implementation needed for optimization. The class hierarchy gives us the ability to use models from full covariances to i.i.d. unit variance noise with a single interface, where the latter will be much cheaper. 

From now on, all non-linear factors take a shared_ptr to a Gaussian noise model. This is done through the parameter (const sharedGaussian& model). The use of a shared pointer allows us to share one noise models for thousands of factors, if applicable.

Just like Richard's Symbol change, there is a compile flag GTSAM_MAGIC_GAUSSIAN which allows you to use doubles, vectors, or matrices to created noise models on the fly. You have to set it to the correct dimension. Use of this is *not* encouraged and the flag will disappear after some good soul fixed all unit tests.

Richard Roberts aef0b42562 Refactoring to use a new Symbol key instead of strings in Bayes*, Gaussian*, Ordering, Symbolic*, VectorConfig. Renamed existing type-checking key Symbol<C,T> to TypedSymbol<C,T> 2010-01-17 19:34:57 +00:00
Alex Cunningham e2bc13a2a6 Renaming gradients -> jacobians 2009-12-18 03:05:47 +00:00
Alex Cunningham a1918056a5 Changed NonlinearConstraints to take cost and gradient functions that do not take the list of keys. Tests have been reconstructed using boost::bind 2009-12-18 02:39:02 +00:00
Alex Cunningham 7d0de77fc6 Changed argument ordering for constraints 2009-12-18 01:40:29 +00:00
Frank Dellaert 9efac7b3fb Some re-naming and re-formatting only 2009-12-15 05:34:49 +00:00
Alex Cunningham e26acc0d8d Changed nonlinear constraints to use boost.bind to handle arbitrary function objects for evaluating cost, useful for parameterizing cost functions. 2009-12-01 19:45:47 +00:00
Alex Cunningham 395e4ae3f1 Fixed sign issue on nonlinear constraints, so that that it is not necessary to flip the sign on the delta configs before using exmap. 2009-11-28 21:00:09 +00:00
Alex Cunningham 0ff7e3a5d9 Changed interface on constraint g(x) and grad_g(x) functions to take a list of keys, so that all of the variables in a factor can be used as necessary. Moved g(x) into base NonlinearConstraint class and some cleanup. 2009-11-28 19:18:02 +00:00
Alex Cunningham 107c6846fb Added basic inequality constraint handling to NonlinearConstraint. Demo still in progress, but now constraints are explicitly handled as either equality or inequality constraints, with an active() function to determine if it is necessary to use the constraint.
Created testOrdering for new subtract() function to remove parts of an ordering.

Alex Cunningham f3e825767b NonlinearConstraints now handle inactive constraints (when the state is already in the feasible region) by returning empty factors on linearization. 2009-11-27 18:42:01 +00:00
Alex Cunningham 714edb57f0 Basic implementation of a binary nonlinear constraint, with working linearization of a binary constraint. 2009-11-20 03:50:48 +00:00
Alex Cunningham ee4a066275 Implemented linearization and equality for unary NonlinearConstraints. Current tests use a scalar example. Split out implementation into a separate implementation file. 2009-11-20 03:04:49 +00:00
Alex Cunningham 429f27550c Added a NonlinearConstraint and testNonlinearConstraint. There is currently an abstract base class for constraints and a partially implemented unary constraint. 2009-11-19 16:50:18 +00:00
