Maybe.
Thanks for #7852 - I didn't know that one. Might as well add #7392
(which I have started on).

I am loathe to involve myself in this conversation, but: I'm aware
that MATLAB is used by people at NASA, in the Navy, and at Raytheon. I
seriously doubt that approaches even a tenth of MATLAB's

You can back out pyc's pretty easy. See the "byteplay" package. :)

Continuing my example:
sage: maxima(f).powerseries('r',infinity)
-4*r*'sum((2^(2*i3-1)-1)*2^(2*i3-1)*bern(2*i3)*r^(2*i3-1)/
(2*i3)!,i3,0,inf)

Hi
Python's barrier-to-entry is the lowest of all the
languages under discussion (in terms of time to learn it).
It is easier to enforce good coding style because much of
it is already integrated with the language... e.g. indented
control structures & loops.

Hi everyone!
I'd like to know if there is a way of finding the series expansion of a
given function around zero and infinity, Is it possible?
I tried with sympy.series, didn't work
sage: reset()
sage: from sympy import *
sage: r = Symbol('r')
sage: sympy.series(2*r/sinh(2*r), r)

Hi!
It seems to me that the patchbot refuses quite a number of patches
since apparently it tries to apply the patches to the latest release
of Sage. But I, for one, often produce my patches on top of a recent
alpha version of the forthcoming release.
I could imagine that it would not be feasible
There is an experimental spkg for vtk. But I think it needs some serious
updating; last time I tired it, it did not compile on my machine. Though you
might want to give it a try.

Has anyone compiled VTK, http://www.vtk.org/, into sage? I would like
