Estimate of Bounds on the Minimum Eigenvalue of the Hadamard Product of a Nonsingular M-matrix and its Inverse
Wang Hui-y · Journal of Guizhou University · 2013
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.
