Re: [Numpy-discussion] User Guide

Hi, I see the desire for stylistic improvement by removing the awkward parens but your correction has incorrect grammar. One cannot have "arrays of Python," nor are Numpy objects a subset of "Python" (because Python is not a set) -- both of which are what your sentence technically states. I.e., th

David, I'm confused about your reply. I don't think Ruben was only asking why you'd ever get non-zero error after the forward and inverse transform, but why his implementation using lists gives zero error but using arrays he gets something of order 1e-15. On Mon, Apr 20, 2009 at 9:47 AM, David Co
