Detailed Description

template<class GO, class PrecGO, template< class > class Solver>
class Dune::PDELab::ISTLBackend_SEQ_MatrixFree_Base< GO, PrecGO, Solver >

Sequential matrix-free solver backend.

This can be used with a combination of {CGSolver, BiCGSTABSolver, MINRESSolver} as a solver and grid operator build from one of the following local operators:

• AssembledBlockJacobiPreconditionerLocalOperator for partial matrix-free Jacobi
• IterativeBlockJacobiPreconditionerLocalOperator for fully matrix-free Jacobi
• BlockSORPreconditionerLocalOperator for matrix-free SOR

Note: If you use BlockSORPreconditionerLocalOperator you need to use FastDGGridOperator!

Template Parameters

GO	Grid operator implementing the matrix-free operator application
PrecGO	Grid operator implementing matrix-free preconditioning
