autocorrelation of two dimensional arrays

Started by aycece May 20, 2008

I have a one dimensional sequence which I construct two dimensional
arrays preserving the autocorrelation properties. I want to calculate
the autocorrelation function of this array and then plot it in 3D. But
I don't want to use the xcorr. Can you recommend me a resource to
write my own code? I will appreciate any help. Thank you very much.
