On Moore----Penrose Inverses Of Matrices a Ring
ABSTRACT
This paper mainly discussed the Moore----Penrose inverses of matrices about general ring matrix and the ring R with an involution * and unitary. And we discussed some sufficient conditions for the existence of Moore----Penrose inverses of matrices over a ring R are given.
Keywords: ring, matrix; *--symmetric; Moore----Penrose inverse.
