Yes.

Use one of the feval functions, declared in parse.h.

It is about as efficient as calling a .oct file function from Octave.

If the functions are defined in the same .oct file, then you can use a
more direct route.  But if they are not in the same file, you may have
unpredictible results, so it is best to use feval to handle the
function (.oct file) lookup.
