一、简介

基于matlab GUI地球自转模拟

二、源代码

function varargout = globegui(varargin)
% GLOBEGUI M-file for globegui.fig created with GUIDE
%
%      Creates a GUI for viewing a spinning Earth globe
%
%      GLOBEGUI, by itself, creates a new GLOBEGUI or raises the existing
%      one.
%
%      H = GLOBEGUI returns the handle to a new GLOBEGUI or the handle to
%      the existing one.
%
%      GLOBEGUI('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in GLOBEGUI.M with the given input arguments.
%
%      GLOBEGUI('Property','Value',...) creates a new GLOBEGUI or raises the
%      existing one. Starting from the left, property value pairs are
%      applied to the GUI before globegui_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to globegui_OpeningFcn via varargin.
