I have 16 values of the period sequence 1, 2, 4, 8, 1, 2, 4, 8, ... I
compute its fourier transform using
>>> from scipy import fft, ifft
>>> x = [1,2,4,8,1,2,4,8]
>>> fft(x)
array([ 30. +0.j, 0. +0.j, -6.+12.j, 0. +0.j, -10. +0.j, 0. +0.j,
-6.-12.j, 0. +0.j])
Now how can I plot these values? I would like to plot 16 values. What
do I need to do here? Can you show an example?
