Eh? What does scipy or numarray have to do with it? Totally different
packages. Especially scipy.


They all provide facilities for array manipulation.

import Numeric
import numarray
import scipy
n = 1500
a_numeric = Numeric.arange(1., n)
a_numarray = numarray.arange(1., n)
a_scipy = scipy.arange(1., n)

I think the confusion results from people using the word 'numpy'  to
refer to the Numeric package, and he numarray package. I actually
cannot find a package which lets me 'import numpy'...

[...5 minutes later with google...]

It seems array stuff has been moved out of scipy core, and into a
numpy package.
From http://numeric.scipy.org/ :

For about 6 months, the new package was called SciPy Core (not to be
confused with the full SciPy package which remains a separate
package), and so you will occasionally see references to SciPy Core
floating around.    It was decided in January 2006 to go with the
historical name of NumPy for the new package.  Realize that NumPy
(module name numpy) is the new name.   Do not be confused by
references to scipy_core. These should all be replaced by numpy.
Also, because of the name-change, there were a lot of dicussions that
took place on scipy-dev@xxxxxxxxx and scipy-user@xxxxxxxxxx

On a different node, I've attached CSV file with results from this
benchmark program, with a third test for scipy.

http://arbutus.mcmaster.ca/dmc/numpy/numcomp.py

Interestingly numarray consistently beats numeric and scipy with
arrays of length greater than 1500. With arrays smaller than 1500,
SciPy and Numeric are often on par with each other.
