摘要
讨论了线性方程Ax=b的Gauss-Seidel迭代法的求解问题.2003年,A.Hadjidimos等提出了预条件矩阵I+Cα.该文证明了若系数矩阵A是H矩阵,则(I+Cα)A是H矩阵.并给出两个数值例子作以说明.
The Gauss-Seidel iterative method for solving linear systems of the form Ax = b is discussed. A.Hadjidimos has proposed a preconditioner I＋C. in 2003. In this paper, if the coefficient matrix A is a Hmatrix, then （I＋Ca）A is also a H matrix. In addition, two numerical examples are given for illustrating the results.
