Is it possible to add a function in MATLAB that automatically wraps my data to a certain range of values?

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.

Adam, thank you for pointing out the error. We've updated the answer to include your suggested change.
