Member Function Documentation

template<typename T >

void Feel::MatrixValue< T >::add	(	const unsigned	int,
		const unsigned	int,
		const value_type	value
	)

inline

Add value to the value already accumulated

template<typename T >

void Feel::MatrixValue< T >::clear ( )

inline

Release all memory and return to a state just like after having called the default constructor.

template<typename T >

void Feel::MatrixValue< T >::close ( ) const

close the gmm matrix, that will copy the content of write optimized matrix into a read optimized matrix

template<typename T >

bool Feel::MatrixValue< T >::closed ( ) const

inline

see if Gmm matrix has been closed and fully assembled yet

template<typename T >

value_type Feel::MatrixValue< T >::energy	(	ublas::vector< value_type > const &	,
		ublas::vector< value_type > const &
	)		const

inline

In this case the energy is the value that has been accumulated

template<typename T >

void Feel::MatrixValue< T >::fill ( pattern_type const & )

fill sparse matrix with non zero entries

template<typename T >

void Feel::MatrixValue< T >::init	(	const unsigned	int,
		const unsigned	int,
		const unsigned	int,
		const unsigned	int,
		const unsigned	int = `30`,
		const unsigned	int = `10`
	)

inline

Initialize a Value matrix that is of global dimension $m \times n$ with local dimensions $m_l \times n_l$ . nnz is the number of on-processor nonzeros per row (defaults to 30). noz is the number of on-processor nonzeros per row (defaults to 30).

References Feel::MatrixValue< T >::zero().

template<typename T >

bool Feel::MatrixValue< T >::isInitialized ( ) const

inline

Returns:: true if matrix is initialized/usable, false otherwise

template<typename T >

matrix_type const& Feel::MatrixValue< T >::mat ( ) const

inline

Returns the read optimized gmm matrix.

template<typename T >

matrix_type& Feel::MatrixValue< T >::mat ( )

inline

Returns the read optimized gmm matrix.

template<typename T >

size_type Feel::MatrixValue< T >::nnz ( ) const

inline

Returns:: the number of non-zeros entries in the matrix

template<typename T >

void Feel::MatrixValue< T >::printMatlab ( const std::string name = "NULL" ) const

Print the contents of the matrix in Matlab's sparse matrix format. Optionally prints the matrix to the file named name. If name is not specified it is dumped to the screen.

template<typename T >

unsigned int Feel::MatrixValue< T >::rowStart ( ) const

inline

return row_start, the index of the first matrix row stored on this processor

template<typename T >

unsigned int Feel::MatrixValue< T >::rowStop ( ) const

inline

return row_stop, the index of the last matrix row (+1) stored on this processor

template<typename T >

void Feel::MatrixValue< T >::set	(	const unsigned	int,
		const unsigned	int,
		const value_type	value
	)

inline

set to value

template<typename T >

unsigned int Feel::MatrixValue< T >::size1 ( ) const

inline

Returns:: m, the row-dimension of the matrix where the marix is $M \times N$ .

template<typename T >

unsigned int Feel::MatrixValue< T >::size2 ( ) const

inline

Returns:: n, the column-dimension of the matrix where the marix is $M \times N$ .

template<typename T >

matrix_type const& Feel::MatrixValue< T >::wmat ( ) const

inline

Returns the write optimized gmm matrix.

template<typename T >

matrix_type& Feel::MatrixValue< T >::wmat ( )

inline

Returns the write optimized gmm matrix.

template<typename T >

void Feel::MatrixValue< T >::zero ( )

inline

Set all entries to 0. This method retains sparsity structure.
