Function Documentation

void viennacl::io::read_kernel_parameters

(

std::string

filename

)

The interface function for reading kernel parameters.

Template Parameters:

VclBasicType

The ViennaCL type for which parameters should be read

Parameters:

filename

Relative filename to the XML file where the parameters are located in

long viennacl::io::read_matrix_market_file	(	MatrixType &	mat,
		const char *	file,
		long	index_base = 1
	)

Reads a sparse matrix from a file (MatrixMarket format).

Parameters:

	mat	The matrix that is to be read (ublas-types and std::vector< std::map <unsigned int, ScalarType> > are supported)
	file	The filename
	index_base	The index base, typically 1

Template Parameters:

MatrixType

A generic matrix type. Type requirements: size1() returns number of rows, size2() returns number columns, operator() writes array entries, resize() allows resizing the matrix.

Returns:

Returns nonzero if file is read correctly

long viennacl::io::read_matrix_market_file	(	std::vector< std::map< unsigned int, ScalarType > > &	mat,
		const std::string &	file,
		long	index_base = 1
	)

long viennacl::io::read_matrix_market_file	(	MatrixType &	mat,
		const std::string &	file,
		long	index_base = 1
	)

long viennacl::io::read_matrix_market_file	(	std::vector< std::map< unsigned int, ScalarType > > &	mat,
		const char *	file,
		long	index_base = 1
	)

long viennacl::io::read_matrix_market_file_impl	(	MatrixType &	mat,
		const char *	file,
		long	index_base
	)

Reads a sparse or dense matrix from a file (MatrixMarket format).

Parameters:

	mat	The matrix that is to be read
	file	Filename from which the matrix should be read
	index_base	The index base, typically 1

Template Parameters:

MatrixType

A generic matrix type. Type requirements: size1() returns number of rows, size2() returns number columns, operator() writes array entries, resize() allows resizing the matrix.

Returns:

Returns nonzero if file is read correctly

		std::string	kernel_name,
		unsigned int	glob,
		unsigned int	loc
	)

		const std::string &	file,
		long	index_base = 1
	)

void viennacl::io::write_matrix_market_file	(	MatrixType const &	mat,
		const std::string &	file,
		long	index_base = 1
	)

Writes a sparse matrix to a file (MatrixMarket format).

Parameters:

	mat	The matrix that is to be read (ublas-types and std::vector< std::map <unsigned int, ScalarType> > are supported)

	index_base	The index base, typically 1

Template Parameters:

MatrixType

A generic matrix type. Type requirements: size1() returns number of rows, size2() returns number columns, operator() writes array entries, resize() allows resizing the matrix.
