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