摘要
根据α-对角占优矩阵与非奇H-矩阵的关系,给出了非奇H-矩阵的新的迭代判别法.该判别法推广和改进了近期的一些结果,并用数值算例说明了文中结果的有效性.
In this paper, some new iterative critetia are given according to the relations of α-diagonally dominant matrices and nonsingular H-matrices, which extend and improve some related results. Effectiveness of these iterative criteria is illustrated by numerical examples.
