摘要:

根据α-对角占优矩阵理论, 运用不等式的放缩技巧, 得到非奇异H-矩阵的几个新判定条件, 推广并改进了已有的对H矩阵的判定方法, 并用数值算例说明了所给判定方法的优越性.

关键词: 非奇异H-矩阵, 对角占优矩阵, 正对角矩阵, &alpha, -对角占优矩阵

Abstract:

Based on the theory of α-diagonally dominant matrices and some techniques for inequlities, several new sufficient conditions to determine nonsingular H-matrices were obtained and thus the corresponding results were improved and generalized. These conditions have improved and generalized some relate existed results for Hmatrices. A numerical example was given to show the advantages of our results.

Key words:  , nonsingular H-matrices; diagonlly dominant matrices; positive diagonally matrices; &alpha, -diagonal dominant matrices
