Abstract
In this paper we will present a fast backward stable algorithm for the solution of certain structured matrices which can be either sparse or dense. It essentially combines the fast solution techniques for banded plus semi-separable linear systems of equations of Chandrasekaran and Gu [4] with similar techniques of Dewilde and van der Veen for time-varying systems [12].
