Gael Guennebaud	3a231c2349	sparse module: add support for umfpack, the sparse direct LU ... solver from suitesparse (as cholmod). It seems to be even faster than SuperLU and it was much simpler to interface ! Well, the factorization is faster, but for the solve part, SuperLU is quite faster. On the other hand the solve part represents only a fraction of the whole procedure. Moreover, I bench random matrices that does not represents real cases, and I'm not sure at all I use both libraries with their best settings !	2008-10-19 22:44:21 +00:00

Gael Guennebaud	ecc6c43dba	sparse module: add preliminary support for direct sparse LU solver ... using SuperLU. Calling SuperLU was very painful, but it was worth it, it seems to be damn fast !	2008-10-19 15:26:28 +00:00
