Detailed Description

template<typename MatrixType, typename VectorType>
class PointerMatrixAux< MatrixType, VectorType >

A pointer to be used as a matrix. This class stores a pointer to a matrix and can be used as a matrix itself in iterative methods.

The main purpose for the existence of this class is its base class, which only has a vector as template argument. Therefore, this interface provides an abstract base class for matrices.

This class differs form PointerMatrix by its additional VectorMemory object and by the fact that it implements the functions vmult_add() and Tvmult_add() only using vmult() and Tvmult() of the MatrixType.

Constructor & Destructor Documentation

PointerMatrixAux() [1/3]

template<typename MatrixType , typename VectorType >

PointerMatrixAux< MatrixType, VectorType >::PointerMatrixAux	(	VectorMemory< VectorType > *	mem = 0,
		const MatrixType *	M = 0
	)

Constructor. The pointer in the argument is stored in this class. As usual, the lifetime of *M must be longer than the one of the PointerMatrixAux.

If M is zero, no matrix is stored.

If mem is zero, then GrowingVectorMemory is used.

Definition at line 676 of file pointer_matrix.h.

PointerMatrixAux() [2/3]

template<typename MatrixType , typename VectorType >

PointerMatrixAux< MatrixType, VectorType >::PointerMatrixAux	(	VectorMemory< VectorType > *	mem,
		const char *	name
	)

Constructor not using a matrix.

This class internally stores a pointer to a matrix via a SmartPointer object. The SmartPointer class allows to associate a name with the object pointed to that identifies the object that has the pointer, in order to identify objects that still refer to the object pointed to. The name argument to this function is used to this end, i.e., you can in essence assign a name to the current PointerMatrix object.

Definition at line 686 of file pointer_matrix.h.

PointerMatrixAux() [3/3]

template<typename MatrixType , typename VectorType >

PointerMatrixAux< MatrixType, VectorType >::PointerMatrixAux	(	VectorMemory< VectorType > *	mem,
		const MatrixType *	M,
		const char *	name
	)

Constructor. M points to a matrix which must live longer than the PointerMatrixAux.

This class internally stores a pointer to a matrix via a SmartPointer object. The SmartPointer class allows to associate a name with the object pointed to that identifies the object that has the pointer, in order to identify objects that still refer to the object pointed to. The name argument to this function is used to this end, i.e., you can in essence assign a name to the current PointerMatrix object.
