[SciPy-user] Obtaining factors of sparse matrices
Thu Apr 2 22:02:25 CDT 2009
I am new to scipy. I would like to compare fill-in between a standard GEPP and
one that I have developed to schedule pivoting in parallel codes. My matrices
are large and sparse. In MATLAB code, I need this:
[L,U] = lu ( A )
I have looked at the scipy documentation and I believe the function I am looking
for is sparse.linalg.splu (...). I do not know what permc_spec means. Neither
I nor Google know what a "factored_lu" object is. And I don't understand the
instruction: "See scipy.sparse.linalg.dsolve._superlu.dgstrf for more info."
Neither does Google.
Any help would be appreciated. I am kind of crunched for time and thought I'd
see if scipy lived up to the hype. Please help scipy live up to the hype.
