非奇异H-矩阵的一类新判定
A TYPE OF NEW CRITERIA FOR JUDGING NONSINGULAR H-MATRICES

本文研究了非奇异H-矩阵的数值判定问题. 利用不等式的放缩方法, 获得了一类判别非奇异H-矩阵的新判据, 推广了相关已有结果, 并通过数值实例说明了本文结果判断范围的更广泛性.
The numerical criteria for judging nonsingular H-matrices is studied in this paper. A type of new criteria for identifying nonsingular H-matrices is obtained by applying some techniques of inequalities, which extends some related and existed results. The universality of the proposed criteria is illustrated by a numerical example
