Hi: Friends, i am busy with developing a CFD code with c++ language and Finite Volume Method. So would you please give me some information about the free code for large sparse matrix linear solver. Regards

Thank you very much for your quick response, but i think it need time to master the packaes that you just mentioned. I want to know if there are some easy to study codes. regards

UMFPACK is quite simple but performs (if I'm not wrong) only direct LU decomposition. Luca

please send me sparse matrix in c
