| 摘 要： | 为了给出M矩阵及与其逆的Hadamard积的最小特征值的准确下界,在M.Fiedler等人研究工作基础上,结合n阶行或列严格对角占优矩阵的一些性质,给出了M矩阵及与其逆的Hadamard积的最小特征值的一个新的下界。算例结果表明,该结果优于已有的结果。

| Abstract: | In order to give M-matrix and its inverse lower bound for eigenvalue of Hadamard product,on the basis of M.Fiedler＇s research,by combining with the properties of diagonally dominant matrix for nth order rows or columns,M-matrix and its inverse lower bound for eigenvalue of Hadamard product are given.The result shows that it is better than the existing results. |
