摘要
In this paper, the mixed-type splitting iterative method is established for solving the linear system Ax = b, where A is a Z-mattix. The iterative method contains an auxiliary matrix L-1(D-1) that is restricted to be nonnegative strictly lower triangular (diagonal) matrix. Comparison theorems show that the proper choice of the L-1(D-1) can lead to the convergence rate of the Mixed-Type Iterative Method faster than that of the SOR and AOR type iterative methods for solving Ax = b. Numerical results are presented. (C) 2007 Elsevier B.V. All rights reserved.
