Octave is written in a combination of C++, C, and Fortran.  Calling
the C++ parts from C would probably lead to problems.  If you are
using C++, you can call any of the functions in the liboctave library
fairly easily, but currently it works best if you are creating .oct
files, not standalone applications.  For the FFT example you mention,
would just be something like:

  #include appropriate headers

  Matrix m (n, m);

  // fill in values for m.

  ComplexMatrix result = m.fourier ();

Take a look at the Octave source for other examples.
