Detailed Description

template<typename T>
class BiTransfer< T >

Class templates for transfer operators based on multilinear ansatz functions over bisected grids.

The templates depend on a type T. This type should satisfy the conditions listed in small_matrix.hpp for small matrices.

Date:: Oct. 25, 2004 - created

Constructor & Destructor Documentation

template<typename T>

BiTransfer< T >::BiTransfer ( unsigned the_disp_type ) [inline]

Constructor which sets the display type.

Parameters:

[in] the_disp_type The display type

Member Function Documentation

template<typename T>

void BiTransfer< T >::PrintParam ( ) [inline, virtual]

Prints the name of the transfer object and (optionally) the parameters.

Implements SysTransfer< T >.

template<typename T>

virtual bool BiTransfer< T >::ProperGrids	(	const Array< int > &	p_domain_size,
		const Array< int > &	p_range_size
	)			`[inline, virtual]`

Returns true if the grid sizes may correspond to the domain and the range of the prolongation (or the range and the domain of the restriction).

Parameters:

`[in]`	p_domain_size	For the domain of the prolongation
`[in]`	p_range_size	For the range of the prolongation

Note:: The grid sizes corresponding to the same dimensions should be either halved or equal.

Implements Transfer< T >.

template<typename T>

void BiTransfer< T >::Prolong	(	MultiVector< T > &	src,
		MultiVector< T > &	dst
	)			`[inline, virtual]`

Prolongs the coarse grid.

This is implemented as computation of halved sums of manyfolds of the grid. We do it recursively and start with the manyfolds of the smallest dimensionality.

Parameters:
