摘要
利用矩阵的有向图引入k-path覆盖α-对角占优矩阵概念,讨论后k-path覆盖α-对角占优矩阵为非奇异H-矩阵(广义严格对角占优矩阵)的充要条件,进而得到了非奇异H-矩阵的新的判定条件.
In this paper, take theadvantage of matrixdirected graph, Introduce the concept of κ-path path cover cover α-diagonally dominat matrix. And then, we discuss that a matrix is κ- α- diagonallly dominat matrix if and only if it is strictly generalized diagonally and furthermore, we obtain some new decision critera for nonsingular H-matrix.
