MATLAB: Transform angles that are -180 to +180 to angles that are in the 0-360 degree range

anglesif statementvector coding

I am implementing a vector coding technique in matlab using the atan2d(diff(y),diff(x)) function, but the results are from -180 to +180 and I would like to have a 0-360 range. I tried to input an if statement for angles < 0 to have 360 added to them, but I couldn't get it to work. It is possible that I just didn't write the statement correctly, but I would appreciate any tips or advice.

This is my little anonymous function that I use for such problems:

Angles360 = @(a) rem(360+a, 360);                        % For ‘atan2d’

Try this:

Angles180 = @(a) rem(180+a, 360)-90;
Result = Angles180([-90, 0, 90])
Result =
     0    90   180

Hi, you can have a look at the following to wrap the angles between the interval [-180:180]

Sa = sparameters('default.s2p');
data = rfparam(Sa,1,1);
rfplot(Sa,1,1,'angle')
func1 = @(x)180*angle(x)/pi;
figure; plot(Sa.Frequencies,func1(data))

Hope this helps!
