Explicit representations and computation of W-weighted Drazin inverse
Chao Gu, Guorong Wang · Journal of Shanghai Normal University · 2006
In this paper,we establish some new explicit representations of the W-weighted Drazin inverse A_(d,w)in terms of regular inverse.By these new representations we can reduce the cost on computation.Also,we consider a rank equation and derive a method for computing W-weighted Drazin inverse.
