Inheritance diagram for F_CrLS:
Purpose: Stiefel Conjugate Residual, used for indefinte linear systems Used to solve a set of linearized differencial equations,.... Some restoration are of the style: A * iNew = iOld iNew could be X, and iOld could be b. Paper: "Templates for the Solution of Linear Systems: Building Blocks for Iterative Methods", R. Barrett, M. Berry, Tony F. Chan, J. Demmel, J. Donato, J. Dongarra, V. Eijkout, R. Pozo, C. Romine, Henk Van der Vorst, All & Utrecht University, All & Netherland, 1994. www.netlib.org
