摘　　要：非奇异H矩阵在许多领域都发挥着重要作用,但在实用中判别H矩阵却是困难的.给出了判定非奇异H矩阵的迭代算法,算法的迭代速度更快.数值算例说明了该算法是有效的.The nonsingular H-matrix can find its application in many fields,yet quite difficult to distinguish in practice.A new iterative algorithm for distinguishing H-matrices is proposed,which has helped improve some of the relevant results.And the iteration velocity of the algorithm becomes faster.Numerical examples also further prove its effectiveness.

关 键 词：非奇异H矩阵 对角占优 迭代算法
