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