[ret1, ret2] = wrap_f_dfdp (f, dfdp, varargin) f and dftp should be the objective function (or "model function" in curve fitting) and its jacobian, respectively, of an optimization problem. ret1: f (varagin{:}), ret2: dfdp (varargin{:}). ret2 is only computed if more than one output argument is given. This manner of calling f and dfdp is needed by some optimization functions.
