linking to SparseQR as a shared library results in a performance hit. The proper way is to link the static library.
...
add prepareLinear to NonlinearOptimizer so that some computation can be cached and does not happen every time.

1. to link with mac veclib, the compiler needs -DYA_BLAS, I changed matrix.cpp to handle both YA_BLAS and the linux's CBLAS flag
...
2. so the current plan is that linux just enables USE_BLAS_LINUX in configure.ac, and macos enables USE_BLAS_MACOS. Those two should be independent given USE_BLAS passed by the user when calling configure.
2010-03-16 21:16:36 +00:00

put Factorization class in its own file, and added checks in constructors that take shared pointers, so we get some more meaningful output rather than *segmentation error*

Added pure cblas implementation of multiplyAdd functions. This does not have autotools support yet, so to enable, goto cpp/Makefile.am, comment out the block concerning GSL/ATLAS, and uncomment the above section enabling just blas.

Major check-in: there are now two interchangeable implementations of VectorConfig.
...
VectorMap uses a straightforward stl::map of Vectors. It has O(log n)
insert and access, and is fairly fast at both. However, it has high overhead
for arithmetic operations such as +, scale, axpy etc...
VectorBTree uses a functional BTree as a way to access SubVectors
in an ordinary Vector. Inserting is O(n) and much slower, but accessing,
is O(log n) and might be a bit slower than VectorMap. Arithmetic operations
are blindingly fast, however. The cost is it is not as KISS as VectorMap.
Access to vectors is now exclusively via operator[]
Vector access in VectorMap is via a Vector reference
Vector access in VectorBtree is via the SubVector type (see Vector.h)
Feb 16 2010: FD: I made VectorMap the default, because I decided to try
and speed up conjugate gradients by using Sparse FactorGraphs all the way.

All std::map<Symbol,T> are now SymbolMap<T>, which is just a thin wrapper around std::map. at(Key) is used instead of first checking with find when an exception should be thrown for non-existent keys. This does not change any behavior or timing currently. This check-in also includes some functions in BayesTree for gathering clique statistics.
