Why autocorr(x) and xcorr(x,x) give different results?

I was trying to find the autocorrelation of a matrix 'x' using autocorr, however cross correlation function (xcorr) is giving me the expected results. The code used is given below, what could be the reason? is there a method by which they can be made equal?

x=randi([0 1],1,64);   %Random values 0 & 1
aut_x=autocorr(x);     % autocorrelation function of x
crs_x=xcorr(x,x);      % cross correlation function of x with itself
