Good morning everyone!
I have the following look-up table.
Basically, this table contains a sample that goes from -180 to 180deg and i would like this sample to be repeated with a period of 2*pi. (To be more clear, the input of the table goes from from -inf to +inf but the table manages only -180 to 180deg).
Is it possible?

Ran in:
theta = (-180:180);
x = randn(size(theta));
% Look up table/interpolant
F = griddedInterpolant(theta, x);
% wrap the input to +/-180
y = F(25)
y = -1.1305
y = F(wrapTo180(746))
y = -0.2496
