摘要
推广了"非奇H-矩阵的条件"一文中的主要结果,得到一类特殊矩阵为非奇H-矩阵的充分必要条件.
The nonsingular H-matrix is important in the numerical analysis and matrix theory＇s research.This article promotes the main result in an article named ＂the condition of nonsingular H-matrix＂,obtains the necessary and sufficient condition of a kind of special matrix about nonsingular H-matrix.
