Calculation of autocorrelation matrix

I want to calculate autocorrelation matrix of a give sequence in matlab.
Which command I have to use ?
>> x=[-2 1 4 2 1 5 4 2 4]
>> z=autocorr(x)
I am getting auto correlated values in a vector form.
I want to calculate Rxx which is a matrix. Suppose if the length of the vector ix N I have to get N X N matrix.
I tried corrmtx( ) but not worked.
Please some one answer my question..

I don't have the econometrics toolbox, but from this:
it looks like you might be able to build it by using the vector and the TOEPLITZ function (or cousins).

Could you just look into it??
Using autocorr is correct here or to use xcorr is correct??
Just try in MATLAB..!!!
Than we can use Toeplitz,...!!
