| Abstract: | The estimation of the upper bound or lower bound of eigenvalue of maximum of Hadamard products of two matrices is given by using the definition of directed graph k-path covering.The relative results are improved,which make the estimation more superior. |

| Keywords: | non-negative matrix Hadamard product eigenvalues estimate |
