摘要：
Properties of the Drazin inverse of the matrix F = ((I)(E) (I)(0)) with E square, are investigated. Based on this approach, it is obtained an explicit formula for the Drazin inverse of matrices of the form A = ((I)(Q) (Pt)(UVt)), where U, V, P and Q are n x k. The representation for A(D) is given in terms of k x k matrices involving the individual blocks under some conditions. Some special cases are also analyzed. (c) 2005 Elsevier Inc.
