Abstract:
This paper discusses the preconditioner for solving the linear system Ax = b,
where A is of the form M-matrix. The paper review of Li-ying Sun [Journal
of Computational and Applied Mathematics, 181(2005); 336 − 341]. Numerically
that the improving modified Gauss-Seidel method, which was referred to as the
IMGS method, the spectral radius of the preconditioned IMGS method is smaller
than that of the SOR method and Gauss-Seidel method. Numerical simulation using
some size of A show that the convergence rate of IMGS method can be increased
using the preconditioner
