%% 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.
