[Numpy-discussion] EuroScipy abstract submission deadline extended

Given that we have been able to turn on registration only very late, the EuroScipy conference committee is extending the deadline for abstract submission for the 2010 EuroScipy conference. On Thursday May 20th, at midnight Samoa time, we will turn off the abstract submission on the conference site

Re: [Numpy-discussion] newbie: convert recarray to floating-point ndarray with mixed types

If you want to do it in just one line (the third line below), this seems to work - unless you have zillions of types in the structured array it should be plenty fast, too: >>> import numpy as np >>> A = np.array([(1.0, 2), (3.0, 4)], dtype=[('x', float), ('y', int)]) >>> array([A[n] for n in A.dty

Re: [Numpy-discussion] faster code

Well, actually np.arange(2**24) was just to test the following line ;). I'm particularly concerned about memory consumption rather than speed. On 16 May 2010 22:53, Brent Pedersen wrote: > On Sun, May 16, 2010 at 12:14 PM, Davide Lasagna > wrote: > > Hi all, > > What is the fastest and lowest m

[Numpy-discussion] faster code

Hi all, What is the fastest and lowest memory consumption way to compute this? y = np.arange(2**24) bases = y[1:] + y[:-1] Actually it is already quite fast, but i'm not sure whether it is occupying some temporary memory is the summation. Any help is appreciated. Cheers Davide

Hi Allen, If you google on "python user input" you already have your answer... for instance: http://en.wikibooks.org/wiki/Python_Programming/Input_and_output Hope this helps, David > Hi all, > Am creating a script to do least square adjustment of levelling data. How do > I get user input into

[Numpy-discussion] Array input

Hi all, Am creating a script to do least square adjustment of levelling data. How do I get user input into a 1D array of intergers. Thanks in advance. Allan maungu.___ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailma
