GUI数据传递userdata

function varargout = lsss(varargin)% LSSS MATLAB code for lsss.fig%      LSSS, by itself, creates a new LSSS or raises the existing%      singleton*.%%      H = LSSS returns the handle to a new LSSS or the handle to%      the existing singleton*.%%      LSSS('CALLBACK',hObject,eventData,handles,...) calls the local%      function named CALLBACK in LSSS.M with the given input arguments.%%      LSSS('Property','Value',...) creates a new LSSS or raises the%      existing singleton*.  Starting from the left, property value pairs are%      applied to the GUI before lsss_OpeningFcn gets called.  An%      unrecognized property name or invalid value makes property application%      stop.  All inputs are passed to lsss_OpeningFcn via varargin.%%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one%      instance to run (singleton)".%% See also: GUIDE, GUIDATA, GUIHANDLES% Edit the above text to modify the response to help lsss% Last Modified by GUIDE v2.5 27-Nov-2013 10:44:06% Begin initialization code - DO NOT EDITgui_Singleton = 1;gui_State = struct('gui_Name',       mfilename, ...
