拟对角占优和M矩阵的判定

The Criteria of imitative Diagonally Dominant Matrices and M-Matrices

以拟对角占优矩阵为媒介，得到了Ｍ矩阵与道Ｍ矩阵的新的判定准则，使Ｍ矩阵与逆Ｍ矩阵的判定更加直观快捷，并且扩大了判定范围．

in this paper, the new criteria of M -matrices andinverse M-matrices are gotten by using imitative diagonallydomings matrices, it can decide M -matrices and inverseM -matrices obviously and promptly, and the deciding scopeis enlarged.
