Bug 570

Summary: SuperLU factorize does always compute full factorization
Product: Eigen Reporter: Philippe Marti <philippe.marti>

Description Philippe Marti 2013-03-20 21:47:42 UTC
It seems to me that any call to SuperLU<>::factorize() performs a complete factorization of the matrix while the documentation presents it as the numerical factorisation step of the whole process. 

I need to update my matrix without changing its structure and reuse as much as possible from the previous computation. The SuperLU<>::options() routine doesn't help as the options get reset to the default values in SuperLU<>::factorize().
