Autocorrelation function/Spectral density

simone pilozzi
Hi all,
does anyone have any suggestion / example on how to compute the spectral density of a time series (e/ o the autocorrelation function)?
The ideal benchmark is the discrete fourier transform of R or Matlab.
Thanks in advance

There’s a fourier transform in QuantLib – in the “ql/experimental/math” directory.
