一、简介

基于matlab时钟设计

二、源代码

function timeCompass()
%h_comaps = compass([x1;x2;x2],[y1;y2;y3])
%x1y1 x2y2 x3y3 为三个指针向量 h_compass为句柄

%%创建坐标轴做为显示表盘,并隐藏
hAxes = axes('visible','off','DrawMode','fast'); 

%%绘制表盘中心点
hAxesDot = axes('Visible','off','DrawMode','fast');
axis equal;
line(0,0,'Parent',hAxesDot,'Marker','o','MarkerFaceColor','k','MarkerSize',15)

 try
  while 1
      %%获取当前时间
      time = floor(clock); %向下取整  clock：将当前时间和日期返回到一个（6元）数组中。
      hour = time(4);      % 2008    8    26    12     31    32.75
      min = time(5);
      sec = time(6);
      %fprintf(hour);
      argHour = pi/2 - (hour + min / 60) * pi / 6;
      argMin = pi/2 - (min + sec / 60) * pi / 30;
      argSec = pi/2 -sec * pi/30;
      %根据计算的指针弧度值创建表盘和指针
      hCompass = compass(hAxes,[0.5*cos(argHour);0.8*cos(argMin);cos(argSec)],[0.5*sin(argHour);0.8*sin(argMin);sin(argSec)]);
      set(hCompass,'LineWidth',3);%设置线宽
      set(hCompass(3),'LineWidth',1);%设置线宽
      set(hCompass(1),'Color','k');%时针红色
      set(hCompass(2),'Color','k');
      delete(findall(hAxes,'Type','text','-or','linestyle',':'));
     %%绘制数值
     ang = pi /3 ;
     for i=1:12
         if rem(i,3) %3d的倍数     字号12
            text(0.8*cos(ang),0.8*sin(ang),num2str(i),'horizontalAlignment','center','FontSize',12,'Parent',hAxes);
         else
            text(0.8*cos(ang),0.8*sin(ang),num2str(i),'horizontalAlignment','center','FontSize',20,'FontWeight','bold','Color','g','Parent',hAxes);
         end  
         ang =ang -pi/6;
     end
