zhidianyundong.m

这是MATLAB的界面—GUI的几个例子

function varargout = zhidianyundong(varargin)
% ZHIDIANYUNDONG1 M-file for zhidianyundong1.fig
%      ZHIDIANYUNDONG1, by itself, creates a new ZHIDIANYUNDONG1 or raises the existing
%      singleton*.
%
%      H = ZHIDIANYUNDONG1 returns the handle to a new ZHIDIANYUNDONG1 or the handle to
%      the existing singleton*.
%
%      ZHIDIANYUNDONG1('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in ZHIDIANYUNDONG1.M with the given input arguments.
%
%      ZHIDIANYUNDONG1('Property','Value',...) creates a new ZHIDIANYUNDONG1 or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before zhidianyundong1_OpeningFunction gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to zhidianyundong1_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
