Thanks for the advice. I'd like to look into the second option, since the
former would not allow other in-place operations like *= /= **/.
That is a good use case.
Hopefully
the package will be fit to share with this list
The problem, as I understand it, is this:
you have a large array and you want to define objects that (1) behave
like arrays; (2) are derived from the large array (can be computed
from it); (3) should not take much space if only small portions of the
large array are ever referenced.
A simple
Hi Yakov,
Thank you for you kind advice. I ended up doing something simpler and
less arcane.
I first read the baconandeggs interleaved data from a memmap, create a
new writeable memmap based on an unpacked dtype, where bacon and eggs
are in two different 'u1' fields, and then I simply convert

This is a new project I just released.
I know it is C#, but some of the design and idioms would be nice in
numpy/scipy for working with discrete event simulators, time series, and
event stream processing.
Hi,
Do you also know how the situation is with sourceforge/launchpad/trac...
and other popular hosting systems ?
Do they also have these restrictions ?
I've not noticed any problems with sourceforge, nor launchpad - I'm
using them regularly from here. You'd hope that was the case for
Hi,
When solving a quadratic equation I get that alpha =
-3.78336776728e-31 which I believe to be far below machine precision:
finfo(float).eps
2.2204460492503131e-16
But an if statement like:
if alpha == 0:
...
does not catch this. Is there a better way to check for things that
are

Thanks! I think this will help the package attract a lot of users.
A couple of housekeeping things:

Hi Francesc,
Looks like a cool project! However, I'm not able to achieve the
advertised speed-ups. I wrote a simple script to try three approaches
to this kind of problem:
1) Native Python code (i.e. will try to do everything at once using temp arrays)
2) Straightforward numexpr evaluation
3)
Interesting. That makes sense and I suppose that also explains why
there is no function to do this sort of thing for you.

A combination of relative and absolute errors is another common solution,
