Where can I find release notes? (It would be helpful if I can point to a
URL as part of the fedora release)

Hi all,
Mark Lodato outlines how to write ufuncs in Cython at
http://wiki.cython.org/MarkLodato/CreatingUfuncs
This is also a great way of adding generalised ufuncs:
http://projects.scipy.org/numpy/wiki/GeneralLoopingFunctions
Super useful!

Hi all,
I'm trying to help someone out with some problems with pyfftw
(pyfftw.berlios.de). He is seeing an exception,
TypeError: view() takes no keyword arguments
This doesn't only happen when he uses pyfftw but also when he does the
following:
>>> import numpy as np
>>> a=np.arange(10)

hi all,
suppose I have A that is numpy ndarray of floats, with shape n x n.
I want to obtain dot(A, b), b is vector of length n and norm(b)=1, but
instead of exact multiplication I want to approximate b as a vector
[+/- 2^m0, ± 2^m1, ± 2^m2 ,,, ± 2^m_n], m_i are integers, and then

I believe there is an error on this wiki page:

MATLAB
y=x(2,:)
PYTHON
y = x[2,:].copy()
shouldn't the Python version be:
y = x[1,:].copy()
If not, please advise.

We are trying to build and test mpl installers for python2.4, 2.5 and
2.6. What we are finding is that if we build mpl against a more
recent numpy than the installed numpy on a test machine, the import of
mpl extension modules which depend on numpy trigger a segfault.
Eg, on python2.5 and python2

Works for me:

from StringIO import StringIO
np.loadtxt(StringIO(s), skiprows=11)

I don't see this behaviour. Could you provide a code snippet?

Hi all,
Is the value of skiprows in loadtxt restricted to values
in [0-10] ?
It doesn't work for skiprows=11.

Good day, me again.
I have this string of data :
String = 'i want\nto go\nto the\nbeach'.
I want to rotate this data to left, or to right, after is split it after '\n'.
Note that it's important to use 'U' array, because i might have unicode
characters in this string.
So normal, the text is:

Thank you for your help. :)
I used this :
try: NData[ (NData==transparent)[:len(OData)] ] = OData[
(NData==transparent)[:len(OData)] ]
except: pass
That means overwrite all "transparent" data from NData with valid data from
OData.
