Re: solving Ax=b with sparse A

I am trying to solve Ax=b problem, where A is a sparse matrix. The
matrix A is saved in compressed column format.

If your matrix is positive definite, I would recommend you TAUCS

http://www.tau.ac.il/~stoledo/taucs/

Otherwise, try UMFPACK

http://www.cise.ufl.edu/research/sparse/umfpack/

Both takes compressed column format.

I have also tried once MUMPS

http://graal.ens-lyon.fr/MUMPS/

It is also not bad but you have to get a F90 compliler to compile it.

Best wishes,
