coordinates_to_planar_indices()

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

Convert coordinates to planar indices (channel vector + frame index).

Parameters

coords	N-dimensional coordinates.
dimensions	Dimension descriptors.

Returns

Pair of {channel_index, frame_index} for planar access.

Note

Only works with planar organization strategy.
