matlab从入门到精通第9章书后源码对初学者很有帮助

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