Abstract

To solve certain type of matrix equations and extend the notions of the Drazin-star and star-Drazin matrices, we define two new classes of rectangular matrices called the outer-star and star-outer matrices. We characterize these new matrices by algebraic and geometrical point of view and give properties of projectors determined by them. Various representations of outer-star and star-outer matrices as integral representations and limit representations are derived. We establish relations between outer-star and star-outer matrices with appropriate nonsingular matrices. Possible applications of outer-star and star-outer matrices in solving some systems of linear equations are presented.
