function varargout = lihaojin(varargin) % LIHAOJIN M-file for lihaojin.fig % LIHAOJIN, by itself, creates a new LIHAOJIN or raises the existing % singleton*. % % H = LIHAOJIN returns the handle to a new LIHAOJIN or the handle to % the existing singleton*. % % LIHAOJIN('CALLBACK',hObject,eventData,handles,...) calls the local % function named CALLBACK in LIHAOJIN.M with the given input arguments. % % LIHAOJIN('Property','Value',...) creates a new LIHAOJIN or raises the % existing singleton*. Starting from the left, property value pairs are % applied to the GUI before lihaojin_OpeningFcn gets called. An % unrecognized property name or invalid value makes property application % stop.
