I am trying to plot angles and would like to have a function that automatically wraps my data to a certain range of values.

For example, if I want my angles to be in the range of between -180 to 180 degrees, then I would like the angle -220 degrees to be converted to 140 degrees.

The ability to automatically convert a number to wrap around a certain range of values is not available as a built-in function in MATLAB 7.6 (R2008a).

However, the following wrapping functions are available in the Mapping Toolbox:

WRAPTO2PI

WRAPTO360

WRAPTO180

WRAPTOPI

These functions make use of the MOD function and some logical operations to achieve the described conversion.

wrapTo180(-220) % requires mapping toolbox
ans = 140

If you do not have access to the Mapping Toolbox or if you want to wrap numbers to an interval other than [-pi,pi], [0,2pi], [-180,180], or [0,360], you can use mod as suggested above or use wrapToInterval() on the file exchange.
