摘要
在椭圆型偏微分方程数值解法中,经常遇到M-阵与Stieltjes-阵,本文进一步拓广M-阵的概念,并研究它们的性质及其在线性方程组迭代解法中的作用.
In the numarical solution of elliptic partial differential equation,M-matrices and Stieltjes matrices are often met, For extending the concept M-matrices,we discuss in this paper the property of M-matrices and generalized M-matrices. Their application to the solution of linear system is also discussed.
