| Abstract: | In this paper,the existence of the group inverse for a class of block matrices is proved by using the sufficient and necessary condition for the existence of group inverses. Meanwhile,the expressions for the group inverse of a class of block matrices are given by the group inverses and elementary transformation of block matrices. |
