Webbthe DMP inverse of a rectangular matrix in the following manner: Definition 2.2. For any matrices A and W, m by n and n by m, respectively, the matrix X = WA d;wWAAyis called the W-weighted DMP inverse of A, and is written as X = AD;y w. Remark 2.3. Obviously, when A 2C m and W = I m, then AD;y w reduces to A D;y. When A 2C m, W = I m and Ind ...
