Well, if you cannot really transpose your matrix, numexpr can also serve as a
good accelerator:
In [1]: import numpy as np
In [2]: import numexpr as ne
In [3]: x_min, x_max, y_min,

2) Subclass the ndarray to do what you want.
I have subclassed ndarray, but I'm not sure how to continue from there.
I was thinking of overriding __getitem__ and casting the complex to my
complex subclass. Would that be the way to go? How would that work with
slices?

Hi,
Can we have a doc wiki merge before the next release? I reviewed everything,
there's changes to about 150 docstrings. See
http://docs.scipy.org/numpy/patch/

I don't see these here. What architecture/compiler/os ?
The system architecture is 2 * Intel Xeon with hyperthreading. The OS
is Red Hat Enterprise (RHE) 4 64-bit running Python 2.5.4. The C
compiler being used is GCC 3.4.6. No Fortran compiler is being used.
That's new to me.
Darn. I

Hi,
I'm pretty sure this is unintentional but I tried easy_install numpy
the other day and it pulled down a 1.4 tarball from PyPI.

Good catch. I just removed the 1.4.0 tarball from PyPI.

Hi,
when compiling numpy-1.40 with the Sun Studio Compilers (v12 Update 1) on Linux
(an OpenSUSE 11.1 in my case), about 30 tests in numpy.test() fail; all
failures are related to the arctan2 function.
I've found that in r7732 a patch was applied to
trunk/numpy/core/src/private/npy_config.h
I previously coded a fortran function that needs a variable number of
scalar arguments. This number is not known at compile time, but at call
time. So I used to pass them within a vector, passing also the length of
this vector

Hi,
I'm trying to install numpy on a WinXP system, on which I have no
administrative rights.
Installation of Python-2.6 went OK, but the windows installer that I
downloaded on sourceforge for numpy (numpy-1.3.0-win32
-superpack-python2.6.exe) gives me an error pop-up window Executing numpy
I don't think I'm on the current version. Does it make sense to move ahead?
Is there a way to suppress the messages?
