To do a 2D FFT on a matrix X, you do 1D FFTs on all the rows, producing X', then you do 1D FFTs on all the columns of X'. So, for a 32x32 2D FFT, you'll end up doing 64 1D FFTs. -- - Tim Roberts, [EMAIL PROTECTED] Providenza & Boekelheide, Inc. -- http://mail.python.org/mailman/listinfo/python-list
