[Bf-committers] Exist a linear algebra library in Blender?

[Sergey Sharybin]

Hi,

We've got Eigen. And i've recently wrote generalized inverse in keyframe
selection algorithm. See
https://svn.blender.org/svnroot/bf-blender/trunk/blender/extern/libmv/libmv/simple_pipeline/keyframe_selection.cc

Function is called pseudoInverse. That's a bit fancier version which deals
with gauges. Just drop zeroing 7 eigen values and you'll have Moore-Penrose
generalized inverse (well, it's a bit modified still -- AFAIR, original
algorithm says SVD decomposition need to be used, but it's much slover than
eigen decomposition, and using eigen decomposition works the same stable
here).
