Function Documentation

template<typename MatrixT >

long viennacl::io::read_matrix_market_file	(	MatrixT &	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, ScalarT> > are supported)
file	The filename
index_base	The index base, typically 1

Template Parameters

MatrixT

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

Examples:

amg.cpp, iterative-armadillo.cpp, iterative-custom.cpp, iterative-eigen.cpp, iterative-ublas.cpp, iterative.cpp, lanczos.cpp, multithreaded_cg.cpp, power-iter.cpp, and spai.cpp.

template<typename MatrixT >

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

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

Note: If the matrix in the MatrixMarket file is complex, only the real-valued part is loaded!

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

MatrixT

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
