A Modified Precondition in the Gauss-Seidel Method

Abstract: In recent years, a number of preconditioners have been applied to solve the linear systems with Gauss-Seidel method (see [1][2][3][4][5][6][7][8][9][10][11][12][13]). In this paper we use S l instead of (S + S m ) and compare with M. Morimoto's precondition [3] and H. Niki's precondition [5] to obtain better convergence rate. A numerical example is given which shows the preference of our method.
