The representation and computation of generalized inverse A_(T, S)~(2)

摘要

This paper presents a novel representation for the generalized inverse A_(T, S)~(2). Based on this, we give an algorithm to compute this generalized inverse. As an application, we use Gauss–Jordan elimination to compute the weighted Moore–Penrose inverse A_(T, S)~(2) and the Drazin inverse Ad.
