unwrap the angle code

Hi, I have a vector of angles which are in the range of -360 to 360. I need to unwrap them. I donot have the wrap and unwrap built in function in my old version of MATLAB.

Could any one come up with a small piece of code to unwrap manually?

Thanks please reply.

Answer 1

Going from a range of -360 to 360 degrees to 0 to 360 degrees is usually called wrapping the angle, not unwrapping. This anonymous function should do the trick:

wrap = @(x)mod(x,360);

Example:

nAngle = -270;
wrap(nAngle)
ans =
    90

Thanks for the answer and correcting me..
