| Abstract: |
| The defination of MB+-matrix is given and its properties that are used to localize the real eigenvalues of a real matrix,and an example is given to verify the effectiveness of this method.The method is better than some other known results. |
| Key words: P-matrices B-matrices M-matrices MB-matrices eigenvalues localization |
