Hi,
I thought I could mention the module we have created for inlining C/C+
+ code
in Python.
You can use it like this:
from instant import inline
add_func = inline("double add(double a, double b){ return a+b; }")
print "The sum of 3 and 4.5 is ", add_func(3, 4.5)
We combine this with the code-generation utilites in GiNaC/Swinginac
to make sort of "Just-in-time compilation"
of finite element python code. This is why I was curious about C code
generation in sympy.
It is a very small module created on top of SWIG. You can find it at
www.fenics.org/instant.
