非奇异H-矩阵的一组含参数细分迭代判定准则

A Set of Subdividing and Iterative Criteria with Parameter for Nonsingular-matrices

根据广义严格α-对角占优矩阵的性质及其与非奇异H-矩阵的关系,利用细分和迭代的方法,得到非奇异H-矩阵的一组细分迭代判定准则,推广和改进了相关结果。

In this paper,based on the properties of-diagonally dominant matrix and its relations with nonsingular-matrices, by the method of subdivided region and iteration,a set of subdividing and iterative criteria with parameter for nonsingularmatrices are obtained.Some related results are improved.
