trig: Common functions to deal with angles.

In Ax3man/trackr: Analyze and Visualize Tracking Data

Description

These functions make it easy to calculate things about orientation and headings, while keeping the angles within -pi to pi.

Usage

angle(x1, y1, x2, y2)

angle_diff(a1, a2)

mean_angle(x)

rotate(x, y, angle)

Arguments

x1	X-coordinate for poinr 1.
y1	Y-coordinate for poinr 1.
x2	X-coordinate for poinr 2.
y2	Y-coordinate for poinr 2.
a1	Angle 1.
a2	Angle 2.
x	A vector of angles.
