| Abstract: | Computing the bounds for the greatest eigenvalue is an important part in the theory of nonnegative matrices.In this paper,we obtained new bounds for the greatest eigenvalue of nonnegative matrices by two new matrices.Compared with the relevant conclusions, the new bounds are more accurate. |
| Keywords: | nonnegative matrices greatest eigenvalue new bounds |
