Detailed Description

The implementation of Trajectory.

Author

Marios Vodas (mvoda.nosp@m.s@gm.nosp@m.ail.c.nosp@m.om).

These functions are documented in the Trajectory/Similarity.h

Function Documentation

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

The function returns the euclidean norm between the trajectories.

Parameters

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