The Conjugate Gradient Method

  • T. Ginsburg
Part of the Die Grundlehren der mathematischen Wissenschaften book series (GL, volume 186)


The CG-algorithm is an iterative method to solve linear systems
$$Ax + b = 0$$
where A is a symmetric and positive definite coefficient matrix of order n. The method has been described first by Stiefel and Hesteness [1, 2] and additional information is contained in [3] and [4]. The notations used here coincide partially with those used in [5] where also the connexions with other methods and generalisations of the CG-algorithm are presented.
