Nicola Mastronardi, Shivkumar Chandrasekaran, Sabine Van Huffel · Numerical Linear Algebra with Applications · 2000
An algorithm for the solution of linear systems of equations where the coefficient matrix is diagonal plus a semi-separable matrix is considered. The algorithm is stable with linear complexity. Furthermore, it is suitable for an implementation on a system of two processors. Copyright © 2001 John Wiley & Sons, Ltd.
