摘要
本文讨论了形如M=[A B C D]分块矩阵的群逆,在一定条件下给出了其具体表达式,所得结果与文[1～3]的结果没有互相包含关系。
The group-inverses of block-matrices,of which forms are M=[_C^A _D^B]are investigated in this parper Also,the concrete expressions are established under some con-ditions. Also,the results and that in [1～3] are uncontained each other.
