| Abstract: | In this paper,we maked a thorough study the compound-type spectral inclusion region of a matrix,given a bouns theorem,and obtained a modified compund-type spectral inclusion.As applications,a new criterion for nonsinguly H-matrices is obtained. |

| Keywords: | Spectral inclusion Nonsingular H-matrix Bound theorem |
