How to wrap angle in degrees to [-180 180] using rfplot(S_params, 'angle')?

When I use function rfplot(S_params, 'angle'), the values of phase are unlimited. But I need the phase values to be between [-180:180] degrees. How can I do that?

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!

Hello,

is this necessary since the rfplot function do not perform the angle wrap when asked to output the angle of the complex number inside the s-parameter oblject. Isn't it something that should be fixed or added as an option?

Thanks
