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