Detailed Description

template<class GO, template< class, class, class, int > class Preconditioner, template< class > class Solver>
class Dune::PDELab::ISTLBackend_NOVLP_BASE_PREC< GO, Preconditioner, Solver >

Utility base class for preconditioned novlp backends.

Template Parameters

GO	The type of the grid operator for the spatial discretization. This class will be used to adjust the discretization matrix. and extract the trial grid function space.
Preconditioner	The type of preconditioner to use.
Solver	The type of solver to use.
