Abstract

In this paper, we characterize the Drazin invertibility of a two by two matrix with zero (2,2)(2,2) entry under some suitable similarity transformation. The results can be applied to obtain detailed Drazin inverse formulae of various structured matrices and some special cases are analyzed.
