◆ load()

bool spla::MtxLoader::load	(	std::filesystem::path	file_path,
		bool	offset_indices = `true`,
		bool	make_undirected = `true`,
		bool	remove_loops = `true`
	)

Load .mtx data from given file path.

Parameters

file_path	Relative or absolute path to file
offset_indices	True if requires indices offset by -1
make_undirected	True if for each directed edge reverse edge must be added
remove_loops	True if self-loops must be removed

Returns: True if successfully loaded

◆ save()

bool spla::MtxLoader::save	(	const std::filesystem::path &	file_path,
		bool	stats_only = `false`
	)

Saves loaded data at file.
