摘要
分析了文献[1-2]中局部双对角占优矩阵的定义,指出了文献[1-2]中结论与其他相关文献的联系。同时,给出了广义严格对角占优矩阵(非奇异H矩阵)的若干充分条件。
By analyzed the definition of local double diagonally dominant matrix in [ 1 - 2 ], we point out the relations between of results in [ 1 - 2 ] and relative results. Simultaneity, some determinate conditions for generalized strictly diagonally dominant matrix are given.
