Traj3DSmoothSG

Smooths a 3-dimensional trajectory using a Savitzky-Golay smoothing filter.

A toolbox to assist with statistical analysis of animal trajectories.
It provides simple access to algorithms for calculating and assessing a variety of
characteristics such as speed and acceleration, as well as multiple measures of
straightness or tortuosity. Some support is provided for 3-dimensional trajectories.
