摘要
本文提出了两类局部双α对角占优矩阵,给出了其为广义严格对角占优矩阵的几个充分条件,并用数值例子说明了所得结果的有效性。
Two kinds of locally α-diagonally dominant matrix are proposed and some sufficient conditions are obtained for judging their generalized strictly diagonally dominance. A numerical example is also given to illustrate the effectiveness of our results.
