广义α-对角占优矩阵与非奇异H-矩阵的判定
Generalized α-diagonally dominant matrix and criterion for nonsingular H-matrix
摘要
Abstract
Concept of α-diagonally dominant matrix is extended to generalized α-diagonally dominant matrix,which is together with zoom technique of inequality used to obtain a new criterin for nonsingular H-matrix.This method makes the criterion for generalized α-diagonally dominant matrices and H-matrices simpler and more effertive more in practice.关键词
