Detailed Description

template<class X>
class RestartedFGMResSolver< X >

implements the Generalized Minimal Residual (GMRes) method

GMRes solves the unsymmetric linear system Ax = b using the Generalized Minimal Residual method as described the SIAM Templates book (http://www.netlib.org/templates/templates.pdf).

Todo:

F durch rebind erzeugen und nur den field_type für F übergeben
