摘要
§1.引言和新方法的提出 设线性代数方程组 Ax=b,(1.1)这里A是n阶非奇异矩阵,x,b是n维向量且b是已知向量,x是未知向量.对于(1.1)的数值解,我们考虑如下的分裂:
In this paper, several generalized preconditioned iterative methods are proposed, the rateof their convergence is analysed and the optimal parameters of τ and ω are determined whe?the coefficient matrix A is symmetric and positive definite. Numerical examples are given.
