function varargout = xiezhh6(varargin) % XIEZHH6 M-file for xiezhh6.fig % XIEZHH6, by itself, creates a new XIEZHH6 or raises the existing % singleton*. % % H = XIEZHH6 returns the handle to a new XIEZHH6 or the handle to % the existing singleton*. % % XIEZHH6('CALLBACK',hObject,eventData,handles,...) calls the local % function named CALLBACK in XIEZHH6.M with the given input arguments. % % XIEZHH6('Property','Value',...) creates a new XIEZHH6 or raises the % existing singleton*. Starting from the left, property value pairs are % applied to the GUI before xiezhh6_OpeningFunction gets called. An % unrecognized property name or invalid value makes property application % stop. All inputs are passed to xiezhh6_OpeningFcn via varargin. % % *See GUI Options on GUIDE's Tools menu.
