摘要
本文根据矩阵A的一系列三元线性不等式组的非空解集的存在性,给出了判定矩阵A为广义对角占优的两个充分条件。
In this paper are given two sufficient conditions to determine a matrix A to be generalized diagonally dominant according to the existence of the nonempty solution sets concerning a series of the systems of linear inequalities in three unknowns for the matrix A.
