Abstract

In this paper we establish the representations for the Drazin inverse A (d) of a square matrix A, based on which we give the Faddeev-type algorithms for A (d) and for the weighted Drazin inverse A d,W of a rectangular matrix A, the Neumann-type expansions and the iterative methods for A (d), and the iterative methods for A (d) based on functional interpolation.
