You can make a mask array in numpy to prune out items from an array
that you don't want, denoting indices you want to keep with 1's and
those you don't want to keep with 0's. For instance,
a = np.array([1,3,45,67,123])
mask = np.array([0,1,1,0,1],dtype=np.bool)
anew = a[mask]
will set anew equal
I agree with Jon here. I can see plenty of motivation for adding the
names asin, etc., but there really isn't a need to remove the current
versions, and it will just introduce compatibility issues when someone
tries to run code written with NumPy 1.x using a NumPy 2.x
installation for even the
If you use iPython and use numpy.linalg.solve??, you can see the
source code of the file numpy/linalg/linalg.py that corresponds to the
solve(a,b) function, not just the docstring:
def solve(a, b):
Solve the equation ``a x = b`` for ``x``.

David said the bug was fixed in the trunk, which you don't have; the
development state of the main source code, or the trunk, is the latest
state available, and releases are always a bit behind trunk since it
would be kind of ridiculous to make a new release every time someone
commits a change.

to manage the tests.

The new testing system works well over here, built on Mac OS X 10.5.2
with GCC 4.2. No errors/failures, but there is that warning Charles

Thanks for the reply. Well, I built my Python stuff, including NumPy
previously, before I changed to the higher GCC version. Do you know if
there's an option I can toggle that will specify Apple's GCC to be
used?
$ CC=/usr/bin/gcc python setup.py build

It's actually pretty simple to compile it yourself once you've

Hello all,
I'm curious if people have experience with / preferences for how to
display a numpy array onscreen as an image.
Pyglet looks relatively easy -- you can feed an image buffer object
with a string or a ctypes pointer.
