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