摘要
通过对分块矩阵的指标集进行划分,利用块严格γ-链对角占优矩阵的定义和性质,并使用不等式的放缩方法,得到判定块严格γ-链对角占优矩阵只与元素有关的条件.
Classified by block matrices of the index set, by using some definition and properties of block γ-diagonally dominant matrix, using inequality scaling method, it got the conclusion that judging block strictly γ -diagonally dominant matrix was just related to the elements.
