| Abstract: | By using the properties of generalized Perron complement,several new estimations of bounds of the Perron root are given for nonnegative matrices bounds,these estimations relax the used conditions or improve the estimating results for several known estimating formulas.Numerical examples are given to illustrate the effectiveness of the results. |
