coordinates_to_linear()

uint64_t MayaFlux::Kakshya::coordinates_to_linear	(	const std::vector< uint64_t > &	coords,
		const std::vector< DataDimension > &	dimensions
	)

Convert N-dimensional coordinates to a linear index for interleaved data.

Parameters

coords	N-dimensional coordinates.
dimensions	Dimension descriptors (size/stride/role).

Returns

Linear index into the underlying data storage.

Note

Only works with interleaved organization strategy. For planar data, use coordinates_to_planar_indices() instead.
