solver for linear system with large sparse matrix
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. |

Re: solver for linear system with large sparse matrix
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 |
