#include <F_CgsLS.hpp>
Inheritance diagram for F_CgsLS:


Purpose: Tranpose Free BiCG, for non symmetric linear systems.
Particularly useful for spared matrices.
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.
