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.
