Shivkumar Chandrasekaran,P. Dewilde,Ming Gu,T. Pals,A. van Veen +4 more
- 18 Dec 2002
TL;DR: This paper combines the fast solution techniques for banded plus semi-separable linear systems of equations with similar techniques of Dewilde and van der Veen for time-varying systems for structured matrices.

Fast stable solver for sequentially semi-separable linear systems of equations
TL;DR: In this article, a fast backward stable algorithm for the solution of certain structured matrices which can be either sparse or dense is presented, which 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.

Approximate Inversion Of Positive Definite Matrices, Specified On A Multiple Band
H. Nelis,Ed F. Deprettere,P. Dewilde +2 more
- 23 Feb 1988
TL;DR: In this paper, a fast algorithm is presented which can be used to compute an approximate inverse of a positive definite matrix if that matrix is specified only on a multiple band and the approximate inverse is the matrix that closely matches the partially specified matrix.
