GUI编程实例

  1 function varargout = GUI013(varargin)
  2 % GUI013 MATLAB code for GUI013.fig
  3 %      GUI013, by itself, creates a new GUI013 or raises the existing
  4 %      singleton*.
  5 %
  6 %      H = GUI013 returns the handle to a new GUI013 or the handle to
  7 %      the existing singleton*.
  8 %
  9 %      GUI013('CALLBACK',hObject,eventData,handles,...) calls the local
 10 %      function named CALLBACK in GUI013.M with the given input arguments.
 11 %
 12 %      GUI013('Property','Value',...) creates a new GUI013 or raises the
 13 %      existing singleton*.  Starting from the left, property value pairs are
 14 %      applied to the GUI before GUI013_OpeningFcn gets called.  An
 15 %      unrecognized property name or invalid value makes property application
 16 %      stop.  All inputs are passed to GUI013_OpeningFcn via varargin.
 17 %
 18 %      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
 19 %      instance to run (singleton)".
