New Lower Bound on the Minimum Eigenvalue for the Hadamard Product of Matrices |

Abstract: | ![]() By using Brauer theorem,a new lower bound on the minimum eigenvalue for the Hadamard product A■A-1 of nonsinggular M-matrix and its inverse is given.Theoretical result and an example demonstrate that the new bound is better than some existing ones. |
