function varargout = Gui3(varargin) % GUI3 MATLAB code for Gui3.fig % GUI3, by itself, creates a new GUI3 or raises the existing % singleton*. % % H = GUI3 returns the handle to a new GUI3 or the handle to % the existing singleton*. % % GUI3('CALLBACK',hObject,eventData,handles,...) calls the local % function named CALLBACK in GUI3.M with the given input arguments. % % GUI3('Property','Value',...) creates a new GUI3 or raises the % existing singleton*. Starting from the left, property value pairs are % applied to the GUI before Gui3_OpeningFcn gets called. An % unrecognized property name or invalid value makes property application % stop. All inputs are passed to Gui3_OpeningFcn via varargin. % % *See GUI Options on GUIDE's Tools menu.
