Classes
class	viennacl::compressed_compressed_matrix< NumericT >
	A sparse square matrix in compressed sparse rows format optimized for the case that only a few rows carry nonzero entries. More...

Namespaces
	viennacl
	Main namespace in ViennaCL. Holds all the basic types such as vector, matrix, etc. and defines operations upon them.
	viennacl::detail
	Holds implementation details for functionality in the main viennacl-namespace. Not intended for direct use by library users.

Functions
template<typename CPUMatrixT , typename NumericT >
void	viennacl::detail::copy_impl (const CPUMatrixT &cpu_matrix, compressed_compressed_matrix< NumericT > &gpu_matrix, vcl_size_t nonzero_rows, vcl_size_t nonzeros)
template<typename CPUMatrixT , typename NumericT >
void	viennacl::copy (const CPUMatrixT &cpu_matrix, compressed_compressed_matrix< NumericT > &gpu_matrix)
	Copies a sparse matrix from the host to the OpenCL device (either GPU or multi-core CPU) More...
template<typename SizeT , typename NumericT >
void	viennacl::copy (const std::vector< std::map< SizeT, NumericT > > &cpu_matrix, compressed_compressed_matrix< NumericT > &gpu_matrix)
	Copies a sparse square matrix in the std::vector< std::map < > > format to an OpenCL device. Use viennacl::tools::sparse_matrix_adapter for non-square matrices. More...
template<typename CPUMatrixT , typename NumericT >
void	viennacl::copy (const compressed_compressed_matrix< NumericT > &gpu_matrix, CPUMatrixT &cpu_matrix)
	Copies a sparse matrix from the OpenCL device (either GPU or multi-core CPU) to the host. More...
template<typename NumericT >
void	viennacl::copy (const compressed_compressed_matrix< NumericT > &gpu_matrix, std::vector< std::map< unsigned int, NumericT > > &cpu_matrix)
	Copies a sparse matrix from an OpenCL device to the host. The host type is the std::vector< std::map < > > format . More...
