Is it possible to use the autocorr to find velocity autocorrelation? I can't make sense of the code here and was hoping to do it another way.

Sorry for silly question, but autocorr takes a 1d vector, but ihave velocity in two direction. v = [cos(angle), sin(angle)]. I don't know how to put it into code..

The conv2 function can deal with 2D autocorrelation
