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