Abdul Shakoor, Hu Yang, Ilyas Ali · DOAJ (DOAJ: Directory of Open Access Journals) · 2014
In this article, we consider representations of the Drazin inverse of a modified matrix M = A−CDdB with the generalized Schur complement Z = D − BAdC under different conditions given in recent articles on the subject. Numerical example is given to illustrate our result.
