摘要
非奇H-矩阵在数值分析和矩阵理论的研究中非常重要,但实际判定一个非奇异H-矩阵却非常困难.给出一类非奇异H-矩阵新的判定条件,改进了近期的相关结果,并用数值例子说明了结果判定范围的更广泛性.
The nonsingular H matrix is important in the numerical analysis and matrix theory＇s research, but it is actually difficult to determine a nonsingular H matrix. The new determination condition is presented in this paper about a kind of Nonsingular H matrix. It improved current related result, and its determination scope is explained more widespread by the numerical example.
