摘要: 应用局部α双对角占优矩阵的概念, 给出广义严格对角占优矩阵及M矩阵的等价表征, 从而推广和改进了已有的相应结果.

关键词: 对角占优矩阵, M矩阵, 等价表征

Abstract: The concept of locally αbidiagonally dominant matrices is used to present some equivalent representations for identifying generalized strictly diagonally dominant matrices and thus the corresponding results are thus generalized.

Key words: diagonally dominant matrix, Mmatrix, equivalent rep resentations
