摘要
本文给出矩阵广义对角占优的若干新判别准则，这些准则允许矩阵为非对角占优，拓广了判别范围．
In this paper, we put forward several new criteria of generalized diagonal domi- nance for matrices. These criteria allow the coefficient matrix A to be not diagonally domi- nant and thus widen the discrimination range of generalized diagonal dominance for matrices.
