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

先按照帮助文档或者案例做一两个例子吧，这种按钮调用callback函数的例子，大部分参考书里面都有，你照着做就行了

如果是运行别人的例子，楼主需要注意两个地方：
1.函数中文件的路径是否正确。
2.函数所在路径是否添加到matlab的路径中。
