Hi, I'm new to Numpy, just bought the guide last week. I've been disappointed by the difficulty I'm having finding functions that are documented in the guide. So far I've had to spend a lot of time tracking down that the fft2 and fftn functions from the fftpack library, which are documented in the numpy guide, are actually in scipy. I've also not been able to find the roll function documented on page 99 of the guide. Did I just buy the guide at a time when it's particularly out of date and there will be an update soon?

Your numpy might be (very) out of date. All of those functions are in numpy 1.0 and later (at least). In [5]: import numpy In [6]: numpy.fft.fft2 Out[6]: <function fft2 at 0x17954f0> In [7]: numpy.fft.fftn Out[7]: <function fftn at 0x1795470> In [8]: numpy.roll Out[8]: <function roll at 0x1475170> -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco
Ahhh... that hadn't occured to me. Just installed Enthon and assumed it was up to date, but it's not. Sorry for the misguided complaint. Thanks, Ross --- Robert Kern <robert.kern@gmail.com> wrote:

No worries. -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco
