[Numpy-discussion] convention in numpy.correlate?

Folks, I need to compute some cross-correlations between time series, and I naturally started to use numpy.correlate. Howver, I'm not sure about the convention being used: The crosscorrelation is usually defined as $\gamma_{xy}[k] = \sum_{i}{x[i] y[i+k]}$ So, when I compute >>> numpy.dot(x[:-1]

[Numpy-discussion] numpy.fftpack: axis=None ?

Folks, I was playing around the numpy.fftpack when I ran into the problem below: it seems that axis=None is not valid with fft. Is there a reason for that ? I was assuming a behavior similar to other functions, where axis=None translates to "use a flat array". ---

[Numpy-discussion] Numpy that is compatible with Scipy windows installer version

I am a Linux user trying to install Numpy/Scipy on a Windows machine in my office. I went to the website and grabbed the two latest versions: scipy = scipy-0.5.0.win32-py2.4.exe numpy = numpy-1.0b5.win32-py2.4.exe Trying to import scipy I get: Python 2.4.3 (#69, Mar 29 2006, 17:35:34) [MSC v.131

Ryan, Try installing the latest scipy version 0.51. There's a windows binary for it. Worked fine for me. Martin Ryan Krauss wrote: > I am a Linux user trying to install Numpy/Scipy on a Windows machine > in my office. > > I went to the website and grabbed the two latest versions: > scipy = sci

I would be glad to try that. Where do I get the installer for scipy 0.51? Thanks, Ryan On 9/6/06, Martin Spacek <[EMAIL PROTECTED]> wrote: > Ryan, > > Try installing the latest scipy version 0.51. There's a windows binary > for it. Worked fine for me. > > Martin > > Ryan Krauss wrote: > > I am

Re: [Numpy-discussion] Numpy that is compatible with Scipy windows installer version

O.K. I think I am up and running. I actually installed Entought and Numpy and Scipy worked together there. I then upgraded the scipy and numpy packages. Is there a compatible matplotlib as well? I was o.k. with mpl from enthought until I switched numerix to numpy. That made mpl unhappy. I down

Re: [Numpy-discussion] Numpy that is compatible with Scipy windows installer version

Ryan, The Enthought 1.0.0 release shipped a pre-release of matplotlib 0.87.3, svn revision 2478. If you update numpy, you have to update to matching versions of scipy and matplotlib. If you are using binary releases, guessing which version of each is needed is difficult unless builders of the
