[vtk-developers] vtkMath::SolveLeastSquares exercised?

Does anybody have any code that exercises the method
vtkMath::SolveLeastSquares added by Tony Pan? I have a system of about
32 equations in 12 unknowns, which should, for the most part, be
independent. But it's not able to construct the pseudo-inverse. I
already found one bug, a minor memory management bug in which the
three-parameter InvertMatrix method wasn't allocating dynamic storage
for index and column when size>10 (I'll be checking in that fix when I
get past this current problem), so that leads me to believe this code
isn't being exercised, at least not for larger systems.

 

Thanks a bunch in advance...

 

Chris
