矩阵对角占优性的推广
Generalization of Diagonal Dominance of Matrices
【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.
【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.
