Abstract
We consider the perturbation formula for the weighted Moore-Penrose inverse of a rectangular matrix and give an explicit expression for the weighted M oore-Penrose inverse of a perturbed matrix under the weakest rank condition . This explicit expression extends the earlier work of several authors. (C) 2000 Elsevier Science Ltd. All rights reserved.
