gui_demo_matlabsky.m

一个MATLAB gui 编程的实例,是初学MATLAB的必备研究实例

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