New inequalities for the Hadamard product of an M-matrix and its inverse
Fu-bin Chen · Journal of Inequalities and Applications · 2015
For the Hadamard product $A\circ A^{-1}$ of an M-matrix A and its inverse $A^{-1}$ , some new inequalities for the minimum eigenvalue of $A\circ A^{-1}$ are derived. Numerical example is given to show that the inequalities are better than some known results.
