[SciPy-user] fft giving error

[Alan Jackson]

I'm trying to run the example from http://linuxgazette.net/115/andreasen.html
to plot the frequency spectrum of sunspot numbers from ipython...

     from scipy import *
     from scipy import fftpack
     
     from scipy.io import read_array
     sunspot = read_array('sunspots.dat')
     
     year=sunspot[:,0]
     wolfer=sunspot[:,1]
     Y=fft(wolfer)

and I get the following error....


In [68]: Y=fft(wolfer)
---------------------------------------------------------------------------
exceptions.TypeError                                 Traceback (most recent call last)

Running gentoo Linux, 2.6.16-gentoo-r3, AMD Athlon X2 64 bit,
blas-atlas-3.7.17
lapack-atlas-3.7.17
scipy-0.5.1
numpy-1.0_rc1
python-2.4.3

Parenthetically, it all builds quite nicely with the gentoo emerge. Kudos
to the gentoo package maintainers.
