摘要
从矩阵的元素出发,利用不等式的放缩技巧,提出了几种广义Nekrasov矩阵的实用判定准则,这些判定准则改进了近期的一些结果,数值算例说明了其有效性.
In this paper, some practical criteria for generalized Nekrasov matrices are given accord- ing to the properties of matrix elements and inequality scaling, which improve some related results. Furthermore, some numerical examples for the effectiveness of the practical criteria are presented.
