| 摘 要： | 本文对迭代求解大型稀疏线性方程组的两个主要方法SOR和AOR迭代与它们的对称方法SSOR和SAOR迭代的收敛速度进行了比较,指出:当系数矩阵为相容次序矩阵时,如果不进行半迭代加速度处理,则对称迭代方法的效率并不高于原迭代方法。

| Abstract: | In this paper we compare the convergence rates of several important methods for iterative solution of large sparse linear systems.We indicate that symmetric iterative methods are not better than basic iterative methods if the former does not use the semi-iterative accelerated techniques. |
