| 摘 要： | 非奇H-矩阵在控制论,经济数学等领域中被广泛的应用,而实际应用中判定非奇H-矩阵是比较困难的.利用广义严格α-对角占优矩阵,得到了非奇H-矩阵的一个实用的判定条件,推广了已有文献的结果,并用数值例子说明了结论的有效性.

| Abstract: | Nonsingular H-matrix is applied widely in control theory,economic mathematics,etc.However,nonsingular H-matrix is determined difficultly in practice.The generalized strictly α-diagonally dominant matrix is applied to obtain a new condition of practical criteria for nonsingular H-matrix.Some results in literature are generalized,and the efficiency of the proposed criteria is showed by a numerical example. |
