template<class Space, class Grid>
class MultilevelTransfer< Space, Grid >
Class that computes and stores prolongation matrices between grid levels.
Template parameter "Space" has to be a function space over a LevelGridView, e.g.
typedef FEFunctionSpace<ContinuousLagrangeMapper<double,Grid::LevelGridView> > H1LevelSpace ;
Example usage (see io/lossystorage.hh):
LevelGridView gv = gridManager.grid().levelView( coarseLevel ) ;
Space space( gridManager, gv, order ) ;
Spaces spaces( &space ) ;
VariableSet varSet( spaces, "y" ) ;
typename VariableSet::VariableSet x( varSet ) ;
// [e.g. set values for x on the coarse level]
MultilevelTransfer<H1LevelSpace,Grid> mlTransfer( gridManager, order, coarseLevel ) ;
// prolongation from coarse grid to levels 1, ..., maxLevel :
for( int l = coarseLevel ; l < maxLevel ; l++ ) {
gv = gridManager.grid().levelView(l+1) ;
space.setGridView(gv) ;
std::unique_ptr<Dune::BlockVector<StorageValueType> > newCoeff=mlTransfer.apply(l, *boost::fusion::at_c<0>(x.data)) ;
*boost::fusion::at_c<0>(x.data) = *newCoeff ;
}TODO: connect to refinement signal for automatic re-calculation in case of grid changes
