Detailed Description

template<typename T>
class libMesh::DenseVectorBase< T >

Defines an abstract dense vector base class for use in Finite Element-type computations. Specialized dense vectors, for example DenseSubVectors, can be derived from this class.

Member Function Documentation

template<typename T>

virtual T libMesh::DenseVectorBase< T >::el ( const unsigned int i ) const [pure virtual]

Returns:: the (i) element of the vector.

Implemented in libMesh::DenseVector< T >, and libMesh::DenseVector< Number >.

Referenced by libMesh::DenseMatrixBase< T >::condense(), and libMesh::DofMap::extract_local_vector().

template<typename T>

virtual T& libMesh::DenseVectorBase< T >::el ( const unsigned int i ) [pure virtual]

Returns:: the (i) element of the vector as a writeable reference.

Implemented in libMesh::DenseVector< T >, and libMesh::DenseVector< Number >.

template<typename T>

virtual bool libMesh::DenseVectorBase< T >::empty ( ) const [inline, virtual]

Returns:: true iff size() is 0.

Reimplemented in libMesh::DenseVector< T >, and libMesh::DenseVector< Number >.

Definition at line 85 of file dense_vector_base.h.

Referenced by libMesh::NumericVector< T >::insert().

{ return (this->size() == 0); }

template<typename T >

void libMesh::DenseVectorBase< T >::print ( std::ostream & os ) const

Pretty-print the vector to stdout.

}

template<typename T >

void libMesh::DenseVectorBase< T >::print_scientific ( std::ostream & os ) const

Prints the entries of the vector with additional decimal places in scientific notation.
