Function Documentation

float8* Manhattan	(	const Trajectory *	trajectoryA,
		const Trajectory *	trajectoryB,
		int32	precision,
		float8 *	result
	)

The function returns the Manhattan norm between the trajectories.

Parameters

[in]	trajectoryA	The first trajectory
[in]	trajectoryB	The second trajectory
[in]	precision	The wanted precision
[out]	result	The result
