In this paper we give formulae for the generalized Drazin inverse M-d of an anti-triangular matrix M = ((A)(C) (B)(0)) in two different ways: one is to express M-d in terms of A(d) with arbitrary B and C. the other is to express M-d in terms of B-d and C-d with arbitrary A. Moreover, the results are applied to obtain generalized Drazin inverses of various structured matrices and some special cases are analyzed. (C) 2010 Elsevier Inc. All rights reserved.
