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