On Moment Methods in Krylov Subspaces

Moment methods in Krylov subspaces for solving symmetric systems of linear algebraic equations (SLAEs) are considered. A family of iterative algorithms is proposed based on generalized Lanczos orthogonalization with an initial vector chosen regardless of the initial residual. By applying this approa...
