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