I noticed on the R mailing list that there is an experimental patch
for Cygwin for complex support: Hopefully there will be support in
Cygwin very soon.
If I recall right, Cephes provides complex.h, which is simply missing
on Cygwin.
Yes, indeed, special functions are also implemented in GSL.
Implementing them well on a FPU
seems to be an art on its own.
Would be nice to have them all under a uniform interface:
gamma.libm, gamma.gsl, etc.

Hi, all,
I'm looking for a kind soul to check the fix for #10741, which deals with
left/right matrix actions on binary quadratic forms (in BinaryQF). The code,
as it is now, does not produce an associative action, i.e.,
Q.matrix_action_right(M).matrix_action_right(N) !=
Q.matrix_actio

We need people to test the new flask-based notebook that was done at the
January Sage Days in Seattle (I believe mainly by Mike Hansen, Rado
Kirov, and Dan Drake). The latest repository of code and instructions
for installing it are here:

Dear all,
Has there been any effort so far in wrapping the root-finding routines
in GSL? Or are there better alternatives for numerical root finding
of vector-valued functions in Sage? All I could find is this "mission
statement", but it doesn't look as if this was ever completed (I'd
love to be
Do you have a trac ticket number? The problem is
is_cython_file = lambda f:fnmatch.fnmatch(f,'*.{pyx,pxd,pxi}')
in parse_deps() in setup.py:633. Python does currently not support
curly-bracket matching:
sage: from glob import glob, fnmatch
sage: is_cython_file = lambda f:fnmatch.fnmatch(f,'*.{
This is a problem I discovered when upgrading from sage-4.5.3 to a
candidate 4.6.2.alpha4. Probably, the problem has existed for a while,
it just "surfaced" or got noticed now.
The problem is that the file
sage/algebras/quatalg/quaternion_algebra_element.cpp
is *not* recreated from the correspond
I respectfully disagree with some of the comments about copy editors.
One doesn't need to be a mathematician or an entry level programmer
to recognize that the installation guide is;
a) one of the first documents that many SAGE users use.
b) in need of some edits, particularly with respect to the s
