Abdul Shakoor, Hu Yang, Ilyas Ali · International journal of applied mathematics and computation · 2014
In this paper, we give some results for the W-weighted Drazin inverse of a modified matrix $M=A-CWD_{d,w}WB$ in terms of the W-weighted Drazin inverse of the matrix $A$ and the generalized Schur complement $Z=D-BWA_{d,w}WC$, generalizing some recent results in the literature.
