关于背景色

背景色是通过这里来设置的：

matlab 复制代码

[X,Y]=meshgrid(linspace(0,1,200));
Z=sqrt((X-.5).^2+(Y-.5).^2);
image([0,100],[0,100],Z.*420);
colormap(flipud(gray))
% colormap(gray)
% colormap(summer)

更换colormap可以试试不同的背景色：

关于叉子或者星星

绘制叉子或者绘制星星是在这里实现的：

matlab 复制代码

plot([85,91.3],[24.8,52.8],'Color',CList(2,:),'LineWidth',18)
% 画叉子的代码
% plot([80,82,92.5,90.7],[28,34.3,31,25.2],'Color',CList(2,:),'LineWidth',18)
% 画星星的代码
StarT=[linspace(0,2*pi,6);linspace(0,2*pi,6)+pi/5];
StarT=StarT(:,1:5);StarT=StarT(:);StarR=[1;cos(pi/5)*2]*ones(1,5);StarR=StarR(:);
fill(cos(StarT).*StarR.*5+85,sin(StarT).*StarR.*5+25,CList(5,:),'LineWidth',2)
fill(cos(StarT).*StarR.*3+85,sin(StarT).*StarR.*3+25,CList(6,:),'EdgeColor','none')

祝MATLABer万圣节快乐！！
