摘要:

利用矩阵分块和矩阵分析方法, 给出一类局部双对角占优矩阵为广义严格对角占优矩阵及其比较阵为M矩阵的充分条件, 拓展了广义严格对角占优矩阵的判定准则.

关键词: 广义严格对角占优矩阵, 非奇异M-矩阵, 判定

Abstract:

Applying the theorem of partitioning of matrices and matrix analysis, some sufficient conditions that local double diagonally dominant matrix is generalized strictly diagonally dominant matrix, i.e. its comparison matrix is M-matrices are given. The criteria for generalized strictly diagonally dominant matrices are generalized.

Key words: generalized strictly diagonally dominant matrix, nonsingular Mmatrices, criteria
