Detailed Description

template<class SOLVER, class VECTOR = Vector<double>>
class MGCoarseGridLACIteration< SOLVER, VECTOR >

Coarse grid solver using LAC iterative methods. This is a little wrapper, transforming a triplet of iterative solver, matrix and preconditioner into a coarse grid solver.

The type of the matrix (i.e. the template parameter MATRIX) should be derived from Subscriptor to allow for the use of a smart pointer to it.

Constructor & Destructor Documentation

template<class SOLVER , class VECTOR = Vector<double>>
MGCoarseGridLACIteration< SOLVER, VECTOR >::MGCoarseGridLACIteration (  )

Default constructor.

template<class SOLVER , class VECTOR = Vector<double>>
template<class MATRIX , class PRECOND >
MGCoarseGridLACIteration< SOLVER, VECTOR >::MGCoarseGridLACIteration ( SOLVER ,
const MATRIX ,
const PRECOND &   
)

Constructor. Store solver, matrix and preconditioning method for later use.

template<class SOLVER , class VECTOR = Vector<double>>
MGCoarseGridLACIteration< SOLVER, VECTOR >::~MGCoarseGridLACIteration (  )

Destructor freeing the pointers.


Member Function Documentation

template<class SOLVER , class VECTOR = Vector<double>>
template<class MATRIX , class PRECOND >
void MGCoarseGridLACIteration< SOLVER, VECTOR >::initialize ( SOLVER ,
const MATRIX ,
const PRECOND &   
)

Initialize new data.

template<class SOLVER , class VECTOR = Vector<double>>
void MGCoarseGridLACIteration< SOLVER, VECTOR >::clear (  )

Clear all pointers.

template<class SOLVER , class VECTOR = Vector<double>>
void MGCoarseGridLACIteration< SOLVER, VECTOR >::operator() ( const unsigned int  level,
VECTOR &  dst,
const VECTOR &  src 
) const [virtual]

Implementation of the abstract function. Calls the solver method with matrix, vectors and preconditioner.

Implements MGCoarseGridBase< VECTOR >.

template<class SOLVER , class VECTOR = Vector<double>>
template<class MATRIX >
void MGCoarseGridLACIteration< SOLVER, VECTOR >::set_matrix ( const MATRIX  )

Sets the matrix. This gives the possibility to replace the matrix that was given to the constructor by a new matrix.
