摘要
本文给出了3-连对角占优矩阵是广义对角占优矩阵的充要条件;也考虑了广义对角占优矩阵的一些简单和实用的判别.
In this paper, we provide a sufficient and necessary condition such that a 3-connective diagonally dominant matrix is a generalized diagonally dominant matrix. Some simple and practical criteria of generalized diagonally dominant matrices are also considered.
