局部α-双对角占优矩阵及其应用

摘要

Based on the concept of local α-double diagonally dominant matrices, several new sufficient conditions to determine generalized strictly diagonlly dominant matrices were given and thus the corresponding results were improved and generalized.%利用局部α-双对角占优矩阵的概念,得到广义严格对角占优矩阵的一些新的充分条件,推广并改进了对广义严格对角占优矩阵的判定方法.
