How can I get the autocorrelation values without the normalization from autocorr ? I just needed the absolute values of autocorrelation. The reasaon I am suspecting that 'autocorr' normalizing is that there difference in 10^3 order between the same autocorrelation vectors I get from Python. The shapes are also same but the values are difference.

Hi Avik,
The documentation for "autocorr" mentions the algorithm used in calculating the autocorrelation. In particular, you can refer to the example mentioned to see how to compare normailzed and unnormalized values :
Hope this helps
