 function varargout = GUI19(varargin)
 % GUI19 MATLAB code for GUI19.fig
 %      GUI19, by itself, creates a new GUI19 or raises the existing
 %      singleton*.
 %
 %      H = GUI19 returns the handle to a new GUI19 or the handle to
 %      the existing singleton*.
 %
 %      GUI19('CALLBACK',hObject,eventData,handles,...) calls the local
 %      function named CALLBACK in GUI19.M with the given input arguments.
 %
 %      GUI19('Property','Value',...) creates a new GUI19 or raises the
 %      existing singleton*.  Starting from the left, property value pairs are
 %      applied to the GUI before GUI19_OpeningFcn gets called.  An
 %      unrecognized property name or invalid value makes property application
 %      stop.  All inputs are passed to GUI19_OpeningFcn via varargin.
 %
 %      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
 %      instance to run (singleton)".
