How to pass the same function to different columns?

I would like to pass the same function to all the columns of an object.

I tried this code but it doesn't work

for j = 1:3
     autocorr(VAR.res(:,j))
 end

where basically I wanted to tell MATLAB "compute autocorrelation for all the 3 columns of VAR.res".

What did I do wrong?

Thanks

That is not an internal Matlab function, unless you meant autocorr. Also, do you want to treat each call as totally separate, or do you want to correlate those columns in some way as well?

Yes, sorry, just edited. I want to treat each call as totally separate

You need to specify the target axes, otherwise the function will use gca for each call, so that will be the same axes.

figure(1),cfl(1)
n_cols=size(VAR.res,2);
for col = 1:n_cols
    ax=subplot(1,n_cols,col);
    autocorr(ax,VAR.res(:,col))
 end

thank you very much! Got it now! thanks again
