摘要
根据α-对角占优矩阵与非奇异H-矩阵的关系,通过对行列指标集作划分,利用Hlder不等式及放缩技巧,给出了非奇异H-矩阵的新迭代判别法则,对已有的相关结果进行了改进和推广,并用数值算例证实了该判定法则的有效性.
A new iterative criteria for nonsingular H-matrices is given according to the relations of a-diagonally dominant matrices and nonsingular H-matrices, and by means of division of row-column index set and by using Holder inequality and its contraction-amplification skill, so that the existing related results are improved and extented. The validity of this criterion is proved by a numerical example.
