I try to calculate the autocorrelation of a signal by using xcorr in this loop:
autc = nan(size(dec.cd{1, 1}));
for k=1:size(dec.cd{1, 1},2)
[rmm, lags] =xcorr(dec.cd{1, 1}(:,k));
rmm = rmm(lags>0);
autc(:,k) = rmm;
end;
I get the error: Subscripted assignment dimension mismatch.
Any idea were the mismatch is?

Looks like it should be
rmm = rmm(lags>=0)
