I hav a matrix of dipole moment and I need to get the autocorrelation funcion. In Python it does with these two lines of code. I am wondering what will be the Matlab equivalent for this two lines,
autocorr_x_full = (signal.fftconvolve(dipole_x_shifted,dipole_x[::-1], mode='same')[(-len(time)):] / np.arange(len(time), 0, -1))
autocorr = autocorr_full[:int(len(time) * fraction_autocorrelation_function_to_fft)]

Hi Avik Mahata
It is my understanding that you want to do convolution and autocorrelation in matlab. You can use Matlab functions 'conv' and'autocorr' for convolution and autocorrelation.
