record operations on the returned tensor. Default: "False".
-[ Example ]-



torch.fft.fftfreq(5)
   tensor([ 0.0000,  0.2000,  0.4000, -0.4000, -0.2000])



For even input, we can see the Nyquist frequency at "f[2]" is given
   as negative:



torch.fft.fftfreq(4)
   tensor([ 0.0000,  0.2500, -0.5000, -0.2500])
