Dear friends,

Could anybody tell me where can I download a solver for linear system with large sparse matrix? I prefer to solver in C or C++. I downloaded the code "sparse1.3" by K.S.Kundert U. of CA, Berkeley, but when I compile it, it shows endless errors.

a good solver (in my opinion) is

http://www-fp.mcs.anl.gov/petsc/

including all kind of Krylov-subspave solvers (GMRES, BISTAB...) and Preconditioning (ILU(n)...)

It solves your equations etc.. also in parallel using MPI, if you want to do this.

I hope that helps,

Frank

P.S: In order to mention also other packages that are available to solve linear equations: http://www.cs.sandia.gov/CRF/aztec1.html
