Yousef Saad This is prepared in the Fortran matrix calculation package (A basic tool-kit for sparse matrix computations (Version 2), contains the common sort, preconditioning (ILU decomposition, etc.), Krylov subspace iteration method, as well as limited differential and other methods such as numerical example. there are many very practical subprogram (such as sparse matrix add, multiply, etc., can learn from experts in the design yo!). hard to study large-scale numerical solution of linear equations of the people Recommended (Fortran is inadequate to achieve, I feel good or C language).
