摘要
文章给出弱不可约严格α-对角占优矩阵的等价表征,并利用按环路α-连对角占优矩阵的理论,给出了若干实用的判定非奇异H-矩阵的新条件,改进了以往的相关结论,并通过数值例子来验证了判定条件的有效性。并由此给出非奇异H-矩阵的若干实用判定条件。
In this paper, the equivalent representation of weakly irreducible strictly diagonally dominant matrices is given.Based on the theory of ring-connected diagonally dominant matrices, some new conditions for judging nonsingular matrices are given, and the related conclusions are improved.The validity of these conditions is verified by numerical examples.
