function varargout = xiezhh5(varargin) % XIEZHH5 M-file for xiezhh5.fig % XIEZHH5, by itself, creates a new XIEZHH5 or raises the existing % singleton*. % % H = XIEZHH5 returns the handle to a new XIEZHH5 or the handle to % the existing singleton*. % % XIEZHH5('CALLBACK',hObject,eventData,handles,...) calls the local % function named CALLBACK in XIEZHH5.M with the given input arguments. % % XIEZHH5('Property','Value',...) creates a new XIEZHH5 or raises the % existing singleton*. Starting from the left, property value pairs are % applied to the GUI before xiezhh5_OpeningFunction gets called. An % unrecognized property name or invalid value makes property application % stop. All inputs are passed to xiezhh5_OpeningFcn via varargin. % % *See GUI Options on GUIDE's Tools menu.
