Generalized inversion and weak bi-complementarity
Hans‐Joachim Werner · Linear and Multilinear Algebra · 1986
In the literature, complementary matrices have been studied because of their importance in statistics. The present paper shows how this notion can be extended to the concept of weak (hi-) complementarity. We will make transparent especially the connections between these new concepts and the concept of generalized inversion. The applications include a method which in certain circumstances allows to determine particular generalized inverses solely by means of regular inversions.
