On the existence of weighted W-Moore-Penrose inverses of rectangular matrices
Chuanning Song · Journal of Shanghai Normal University · 2008
The W-Moore-Penrose inverses of rectangular matrices are defined.Some necessary and sufficient conditions for the existence,some expressions and applications of the weighted W-Moore-Penrose inverses of rectangular matrices are given.And some new necessary and sufficient conditions for the existence of the weighted group inverse introduced by 《The existence of inverses of weighted rectangular matrices》 are proved.
