| Abstract: | Some new lower bounds of the minimum eigenvalues of the Hadamard product of a nonsingularM-matrix and its inverse were given. These bounds improve the related results. The estimating formulas of the bounds only depend on the entries of matrices; therefore, they are easy to calculate. |
