| 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. |
| 关 键 词： | 非奇H-矩阵 对角占优矩阵 不可约 非零元素链 |

| Abstract: | 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. |
| Keywords: | Nonsingular H matrix diagonal-dominant matrix irreducible nonzero chain of element |
