Detailed Description

template<typename VectorType>
class PointerMatrixBase< VectorType >

Abstract class for use in iterations. This class provides the interface required by LAC solver classes. It allows to use different concrete matrix classes in the same context, as long as they apply to the same vector class.

Deprecated:

Use LinearOperator instead

Member Typedef Documentation

value_type

template<typename VectorType>

typedef VectorType::value_type PointerMatrixBase< VectorType >::value_type

Value type of this matrix. since the matrix itself is unknown, we take the value type of the vector. Therefore, matrix entries must be convertible to vector entries.

This was defined to make this matrix a possible template argument to BlockMatrixArray.

Constructor & Destructor Documentation

~PointerMatrixBase()

template<typename VectorType>

virtual PointerMatrixBase< VectorType >::~PointerMatrixBase ( )

virtualdefault

Virtual destructor. Does nothing except making sure that the destructor of any derived class is called whenever a pointer-to-base-class object is destroyed.

Member Function Documentation

template<typename VectorType>

virtual void PointerMatrixBase< VectorType >::clear ( )

pure virtual

Reset the object to its original state.

Implemented in PointerMatrixVector< number >, PointerMatrixAux< MatrixType, VectorType >, and PointerMatrix< MatrixType, VectorType >.

vmult()

template<typename VectorType>

virtual void PointerMatrixBase< VectorType >::vmult ( VectorType &  dst, const VectorType &  src  ) const

pure virtual

Matrix-vector product.

Implemented in PointerMatrixVector< number >, PointerMatrixAux< MatrixType, VectorType >, and PointerMatrix< MatrixType, VectorType >.

Tvmult()

template<typename VectorType>

virtual void PointerMatrixBase< VectorType >::Tvmult ( VectorType &  dst, const VectorType &  src  ) const

pure virtual

Transposed matrix-vector product.

Implemented in PointerMatrixVector< number >, PointerMatrixAux< MatrixType, VectorType >, and PointerMatrix< MatrixType, VectorType >.

vmult_add()

template<typename VectorType>

virtual void PointerMatrixBase< VectorType >::vmult_add ( VectorType &  dst, const VectorType &  src  ) const

pure virtual

Matrix-vector product, adding to dst.
