[SciPy-user] help about sparse matrix

[jose luis Lopez Martinez]

i am working in my thesis of  master and  i will work with sparse matrix and
solve equations of lineal algebra of
A . x  =  B

the size of matrix is 128^4(268,435,456 rows)x 128^4(268,435,456 colums).
the matrix have diagonald dominancies that is a sufficient condition
for convergence of Jacobi iteration , gauss seidel and xor(relaxion method),
but is slow for converge.
it exist a command  in scipy  that solve sparse matrix using at the
Gauss-Seidel iteration method o krylov iterative methods?

thanks
