Namespaces
	plssvm
	The main namespace containing all public API functions.
	plssvm::detail
	Namespace containing implementation details. Should not directly be used by users.
	plssvm::detail::io
	Namespace containing implementation details for the IO related functions. Should not directly be used by users.

Functions
std::size_t	plssvm::detail::io::parse_libsvm_num_features (const std::vector< std::string_view > &lines, const std::size_t skipped_lines=0)
	Parse the maximum number of features per data point given in lines, where the first skipped_lines are skipped. More...
template<typename real_type , typename label_type >
std::tuple< std::size_t, std::size_t, std::vector< std::vector< real_type > >, std::vector< label_type > >	plssvm::detail::io::parse_libsvm_data (const file_reader &reader, const std::size_t skipped_lines=0)
	Parse all data points and potential label using the file reader, ignoring all empty lines and lines starting with an #. If no labels are found, returns an empty vector. More...
template<typename real_type , typename label_type , bool has_label>
void	plssvm::detail::io::write_libsvm_data_impl (const std::string &filename, const std::vector< std::vector< real_type >> &data, const std::vector< label_type > &label)
	Write the provided data and labels to the LIBSVM file filename. More...

void	plssvm::detail::io::write_libsvm_data (const std::string &filename, const std::vector< std::vector< real_type >> &data, const std::vector< label_type > &label)
