% Department. This GUI is tested with Matlab machine in calclab, and works

% FINAL M-file for final.fig
%      FINAL, by itself, creates a new FINAL or raises the existing
%      singleton*.
%
%      H = FINAL returns the handle to a new FINAL or the handle to
%      the existing singleton*.
%
%      FINAL('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in FINAL.M with the given input arguments.
%
%      FINAL('Property','Value',...) creates a new FINAL or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before final_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to final_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
