摘要
根据非奇异H-矩阵的性质构造系数,选取正对角因子,得到了非奇异H-矩阵的几个新的判定条件,并通过数值实例验证了判定条件的有效性.
Several new criteria are obtained for nonsingular H-matrices according to the properties of nonsingular matrices and through constructing the coefficient and selecting the positive diagonal factor.The effectiveness of the results is verified by a numerical example.
