Your numpy might be (very) out of date.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 _______________________________________________ Numpy-discussion mailing list [email protected] http://projects.scipy.org/mailman/listinfo/numpy-discussion
