摘要
提出了一类局部双对角占优矩阵,并据此给出了其为非奇异H-矩阵的新判据,最后通过数值实例说明了所得结果的有效性.
In this paper, a kind of local doubly diagonally dominant matrices is introduced, and some new criteria for nonsingular H-matrices are obtained according to the kind of local doubly diagonally dominant matrices.A numerical example is also given to illustrate the effectiveness of the proposed results in the end.
