The update seems to work for all my students who

If you do not know the size of your array before you finalize it, then
you should use lists whenever you can. I just cooked up a short
example:
##
import timeit
import numpy as N
values = range(1)
def appendArray(values):
Basically, what you want to do is a histogram. Numpy has that
functionality built in. However: the version built in to numpy is about
as suboptimal as yours. The problem is the unnecessary sorting of the data.
In principle, a histogram does not need any sorting, so it could be done
in strictly O(N

Thanks, I'll leave it as is - I was just wondering if there was

Isn't distutils included in python library ? Anyway, scons does not
require anything else than a python

Hi Pearu,
Thanks for reviewing this, especially since you are arguably the
most knowledgeable about this part of numpy :)
Hi,
Examples look good. It seems that you have lots of work ahead;) to add
numpy.distutils features that are required to build numpy/scipy.
Few comments:
1) Why SConstruct does not have extension? It looks like a python file
and .py extension could be used.
2) It seems that scons does not interf
