引进了局部(α,β,γ)-对角占优矩阵的相关概念,在不可约局部(α,β,γ)-对角占优矩阵的条件下,获得了非奇异H-矩阵及非奇异M-矩阵的实用判别准则,推广了已有的相关结果。
The relative concepts of local(α,β,γ)-diagonally dominant matrix is introduced in this paper,under the conditions of irreducible local(α,β,γ)-diagonally dominance,practical criterions of nonsingular H-matrix and nonsingular M-matrix are obtained,extending the existed results.
