Hello, I have a 20000x100 dataset, I know how to run a function (generate surrogate values) for each 100 columns as shown in the code below. "theta" and "AHGT" are each 20000x100 datasets

AHGT1=AHGT(:,1)
Theta1=theta(:,1) 
for s=1:numsurrogate
surrogate_amp1=[AHGT1(skip(s):end); AHGT1(1:skip(s)-1)]; 
surrogate_m(s)=mean(surrogate_amp1.*exp(i*Theta1));
end

What I would like to do is create a loop for each 100 columns and whose output surrogate_m(:,x) array concatenates into a single matrix. This is what I have tried, unsuccessfully.

for w=1:100
AmplitudeHighGamma(w)=AHGT(:,w);
ThetaPhase(w)=theta(:,w);
for s=1:numsurrogate
surrogate_amplitudetotal1=[AmplitudeHighGamma(skip(s):end); AmplitudeHighGamma(1:skip(s)-1)]; 
surrogate_mtotal(s)=mean(surrogate_amptotal1.*exp(i*ThetaPhase));
end
loopsurrogate=[surrogate_mtotal(w)]
end
