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