Bounds on the Minimum Eigenvalues of the Hadamard Product of an M-matrice and Its Inverse
Hui Zhao · Journal of Sichuan University of Science & Engineering · 2011
A new lower bound of the minimum eigenvalues of Hadamard product for inverse A-1 of nonsingular M-matrix A and nonsingular M-matrix B is given.This estimating formula of the bounds are easier to calculate since they only depend on the entries of matrices A and B.The given numerical example show that estimating formula of the bounds is better than several known estimating formulas.
