一、简介

基于matlab GUI时钟设计

二、源代码

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