弱链对角占优M-矩阵A的‖A－1‖∞上界估计
New upper bounds for ‖ A-1‖ ∞ of weakly chained diagonally dominant M-matrices
摘要
Abstract
Let A be a weakly chained diagonally dominant M‐matrix .For the problem of the infinity norm of the inverse matrix ,first some new notations are introduced ,then using the estimator for the elements of inverse matrix and algebra methods ,new upper bounds for ‖A-1 ‖ ∞ are presented .Numerical figure show s that the new upper bound estimates improve some of the current results .关键词
