Robert,
Is there any prediction for when numpy complex types will work?
After applying both http://trac.sagemath.org/sage_trac/ticket/6438
and http://trac.sagemath.org/sage_trac/ticket/4571 , the notebook
seems to work just as well as the command line, or just raw Cython.
Hopefully this makes it into 4.1.1.
As for complex types, there's still some issues of

Robert,
Should those double complex declarations give any speedup?
Yes, lots (compared to using Python complex objects). The are complex
analogues of int, double, float, etc.
Are they declaring the numpy complex type or something else?

Hi everyone,
I thought I'd share the following:

Shouldn't it not give me the negative solution? Also:

Well, I figured it's about time someone did it :). I thought I was
going to have to patch the numpy c sources myself, but shortly after
diving into them I saw the much simpler solution.
Kudos and thanks to Robert
Bradshaw. If I ever meet you, I'd be happy to buy you

recommend creating a patch and trying to get it into Sage proper
(there has been discussion about the lack of easy-to-use stats
support). A lot has changed since 3.2.2.
