1 function varargout = GUI18(varargin)
2 % GUI18 MATLAB code for GUI18.fig
3 % GUI18, by itself, creates a new GUI18 or raises the existing
4 % singleton*.
5 %
6 % H = GUI18 returns the handle to a new GUI18 or the handle to
7 % the existing singleton*.
8 %
9 % GUI18('CALLBACK',hObject,eventData,handles,...) calls the local
10 % function named CALLBACK in GUI18.M with the given input arguments.
11 %
12 % GUI18('Property','Value',...) creates a new GUI18 or raises the
13 % existing singleton*. Starting from the left, property value pairs are
14 % applied to the GUI before GUI18_OpeningFcn gets called. An
15 % unrecognized property name or invalid value makes property application
16 % stop. All inputs are passed to GUI18_OpeningFcn via varargin.
17 %
18 % *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
19 % instance to run (singleton)".
