Member Function Documentation

basis_size()

template<class X >

virtual int CoarseSpace< X >::basis_size ( )

pure virtual

Returns the size of the coarse basis.

Returns

Size of the basis

Implemented in Dune::PDELab::SubdomainProjectedCoarseSpace< GFS, M, X, PIH >.

get_coarse_system()

template<class X >

virtual std::shared_ptr< COARSE_M > CoarseSpace< X >::get_coarse_system ( )

pure virtual

Returns the matrix representing the coarse basis.

Returns

The coarse matrix

Implemented in Dune::PDELab::SubdomainProjectedCoarseSpace< GFS, M, X, PIH >.

prolongate()

template<class X >

virtual void CoarseSpace< X >::prolongate ( const COARSE_V &  coarse, X &  prolongated  ) const

pure virtual

Prolongates a vector defined on the coarse space to the subdomain.

Parameters

[in]	v	The coarse space vector to be prolongated
[out]	prolongated	The prolongation in subdomain space.

Implemented in Dune::PDELab::SubdomainProjectedCoarseSpace< GFS, M, X, PIH >.

restrict()

template<class X >

virtual void CoarseSpace< X >::restrict ( const X &  fine, COARSE_V &  restricted  ) const

pure virtual

Restricts a vector defined on a subdomain to the coarse space.

Parameters

[in]	d	The subdomain space vector to be restricted
[out]	restricted	Resulting restriction in coarse space. Must be of size given by basis_size().

Implemented in Dune::PDELab::SubdomainProjectedCoarseSpace< GFS, M, X, PIH >.
