On the Generalized Shift-HSS Splitting Methods for Nonsingular Saddle Point Problem

Zhuo-hong HUANG, Hong SU

Abstract


In this paper, we establish a generalized shift-HSS splitting (denoted by GSFHSS) iteration method for solving nonsymmetric saddle point system where the (1,1)-block sub-matrix is nonsymmetric positive definite and investigate that the convergence property of the GSFHSS iteration method.
