I'm having problem with the return values of NumPy's vectorize
function. When I pass an array of strings in the following simple
example, vectorize truncates the strings in the returned list. Any
clues of what to do?
Yours, Carl
import numpy as np
def __f(x):
return x
f = vectorize(__f)
Dear friends,
I plan to port a Monte Carlo engine from Matlab to Python. However,
when I timed randn(N1, N2) in Python and compared it with Matlab's
randn, Matlab came out as a clear winner with a speedup of 3-4 times.
This was truly disappointing. I ran tthis test on a Win32 machine and

Common ancenstry, NumPy and Matlab borrowed the name from IDL.

What is the difference between CPython, Python for .NET, and IronPython?
For example, if I'm running IronPython, can I access modules such as Numeric

As I understand it, interoperability with C# and .NET works in both
directions with IronPython, but CPython modules cannot be
