⛄二、部分源代码

function varargout = clock_gui(varargin)
% CLOCK_GUI MATLAB code for clock_gui.fig
% CLOCK_GUI, by itself, creates a new CLOCK_GUI or raises the existing
% singleton*.
%
% H = CLOCK_GUI returns the handle to a new CLOCK_GUI or the handle to
% the existing singleton*.
%
% CLOCK_GUI(‘CALLBACK’,hObject,eventData,handles,…) calls the local
% function named CALLBACK in CLOCK_GUI.M with the given input arguments.
%
% CLOCK_GUI(‘Property’,‘Value’,…) creates a new CLOCK_GUI or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before clock_gui_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to clock_gui_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE’s Tools menu. Choose “GUI allows only one
% instance to run (singleton)”.
%
% See also: GUIDE, GUIDATA, GUIHANDLES

% Edit the above text to modify the response to help clock_gui
