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