The packing of the result is "standard": If A = fft(a, n), then A[0]
contains the zero-frequency term, A[1:n/2+1] contains the
positive-frequency terms, and A[n/2+1:] contains the
negative-frequency
terms, in order of d
The frequencies produced by the two recipies are not the same. But the
DFT is periodic in both frequency and time. So whether you think that the
number in bin in n/2 should correspond to frequency n/2 or -n/2, it's the
same number.

Hi there,
I have a question regarding the definitions surrounding FFTs. The help
to numpy.fft.fft says:
>>> help(N.fft.fft)
Help on function fft in module numpy.fft.fftpack:
fft(a, n=None, axis=-1)
fft(a, n=None, axis=-1)
Will return the n point discrete Fourier transform of a. n
