摘要
研究了判定广义对角占优矩阵的几个充分条件,推广和改进了相关已有结果,并用两个例子说明判定方法的有效性.
In this paper, we study some sufficient conditions for a class of generalized diagonally dominant matrices, which extend and improve some related known results. In addition, we give two examples to illustrate the effectiveness of these criteria.
