Detailed Description

This computes the optimum guess for the system Ax=b in the L2 residual norm. For use in the HMD force calculations using a minimal residual chronological method This computes the guess solution as a linear combination of a given number of previous solutions. Following Brower et al, only the orthogonalised vector basis is stored to conserve memory.
