Let's say, I wrote matrix.c which is a C file containing several functions. Can I call any of the functions defined in matrix.c from Sage? What special compilation do I need for matrix.c?

You can use your C/C++ code directly, using the Ctypes library, which is included in SAGE. You can find a nicely documented example on how to call your libraries on Numerical Sage documentation:

Probably you will want to use Cython to do this - it's a good way to integrate C libraries with Sage (as well as to create C code from within Sage).

You may also want to search this site for Cython for more tips.

There's also ctypes, which I've found useful in the past.
