Hi,
I am trying to plot a line of best fit for some data i have, is there a
simple way of doing it?
Cheers

Hello list,
just a quick follow-up on the managed deallocation. This is what I've
done this week-end:
In numpy.i, I have redefined the import_array() function to also take
care of the managed memory initialisation (the _MyDeallocType.tp_new =
PyType_GenericNew; statement). This means that in

While my feelings aren't as strong as David's, they are pretty much identical.
As a point of reference, Red Hat Enterprise Linux 6 won't come out
until at least the first quarter of 2010. Until then we should make a
serious effort to support Python 2.4, which ships with RHEL 5. It

Hi,
I want to create a matrix based on a vector. It is difficult to describe the
issue for me in english. Here is an example.
Suppose I have an array([3, 6, 8, 12]), I want to create a range based on each
element. In this exampe, let us say want to create 4 number with step 2, so I
will

In looking for simple ways to read and write data (in a text readable format)
to and from a file and later restoring the actual data when reading back in,
I've found that numpy arrays don't seem to play well with repr and eval.
E.g. to write some data (mixed types) to a file I can do this (fp
Hi,
The repr - eval pair does not work with numpy. You can simply do a
tofile() from file().

With just a couple of tweaking, we end up with some decent speed: it's
