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