A modified GPSS method for non-Hermitian positive definite linear systems

摘要

This paper is concerned with a modified version of the generalization of positive-definite and skew-Hermitian splitting iteration (MGPSS) to solve the non-Hermitian positive definite linear systems. The theoretical analysis shows that the MGPSS iteration method will converge unconditionally. Numerical examples are reported to confirm the efficiency of the proposed methods.
