%    The sdoAircraftEstimation_Objective function is used to compare model
%    outputs against experimental data.
%
%    vals = sdoAircraftEstimation_Objective(v,Exp) 
%
%    The |v| input argument is a vector of estimated model parameter values
%    and initial states.
%
%    The |Simulator| input argument is a simulation object used 
%    simulate the model with the estimated parameter values.
%
%    The |Exp| input argument contains the estimation experiment data.
%
%    The |vals| return argument contains information about how well the
%    model simulation results match the experimental data and is used by
%    the |sdo.optimize| function to estimate the model parameters.
