function varargout = gui2(varargin) % GUI2 MATLAB code for gui2.fig % GUI2, by itself, creates a new GUI2 or raises the existing % singleton*. % % H = GUI2 returns the handle to a new GUI2 or the handle to % the existing singleton*. % % GUI2('CALLBACK',hObject,eventData,handles,...) calls the local % function named CALLBACK in GUI2.M with the given input arguments. % % GUI2('Property','Value',...) creates a new GUI2 or raises the % existing singleton*. Starting from the left, property value pairs are % applied to the GUI before gui2_OpeningFcn gets called. An % unrecognized property name or invalid value makes property application % stop. All inputs are passed to gui2_OpeningFcn via varargin. % % *See GUI Options on GUIDE's Tools menu.
