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