You can use it inside an .oct function. See bfgsmin.cc for an example. If 
there is a more straightforward way to do this, I'd be happy to know about 
it. The problem inside bfgsmin is that we don't know how many arguments the 
function to be minimized has. So, they are all collected into a cell array, 
so that feval is called with the function name "celleval" and a single 
argument, which holds the name of the function to be evaluated and its 
arguments.
