Seeking a best solver
 
I am seeking for the best iterative solver. Ax=B. A triangular non positive matrix, i tested a lot of classical solvers but i have some problems with a number of itarations. Thanks

A problem with a triangular matrix can be solved directly with the time proportional to the matrix-vector multiplication time. I don't understand, why should it be solved iteratively. Just for training or testing purposes? Regards ...Gassan.

The AX=B, where A is a triangluar matrix, can be directly solved using 'Blas' matlib or 'lapack' lib, see Intel com's www.
