| Abstract: | In this paper,a new simple-calculating estimation method based on two new matrices are obtained by using the Frobenius inequality.Therefore a convergence sequence of lower bounds and upper bounds of the perron root can be constructed.Some examples are given to show the effectiveness of the new method is effective. |
