Re: OPR-computation-related linear algebra problem
CD let me attach again. I attached the things I intended for the previous post.
As with many of the analysis functions, this calls into a DLL, to the function InvMatrixLUDri_head. So it seems to be using LU decomposition. I think the matrix qualifies as sparse, so that helps with performance.
The direct solver was almost ten seconds.
