Hi,
Is anybody interested in doing either of these SAGE devel projects?
1. Create QDRF -- quad double real field
http://sage.math.washington.edu:9002/sage_trac/ticket/233
This would be like the RealDoubleField in rings/real_double.pyx or
like riungs/real_mpfr.pyx, except that the quad double library is a
C++ library -- so actually this might be similar to the Givaro
wrapper in rings/finite_field_givaro.*.
The quaddouble library (and docs?) are available at
http://www.cs.berkeley.edu/~yozo/
Also, I made a SAGE package, which you get by doing
{{{
sage -i quaddouble-2.1.213.1.spkg
}}}
2. Lie Groups:
http://sage.math.washington.edu:9002/sage_trac/ticket/234
There is an amazing program called Lie for computing with compact Lie groups.
It's available as an optional sage package, e.g.,
{{{
sage -i lie-2.2
}}}
(But check to see if this is the latest version...)
Anyway, for this project, research ways to make a SAGE <--> Lie interface.
Via pexpect? Via C library?
