Autocorr function for each column of a matrix

I want to find the autocorrelation for each column of a matrix, from column 3 to the end of the columns. I also want to store this results in a vector named acorr_yld. I use the following:

if true
  % acorr_yld(1,:) = autocorr(data{4}(:,3:end),1)
end

This setting works for the function mean and std however, this does not work for autocorr. What am I missing? I get the following error:

if true
  % Error using autocorr (line 83)
  % Input series must be a vector.
end
