先稍微说一下原理再去给完整代码哈。 玫瑰花
玫瑰花咋画以及怎么旋转到合适的位置可以参见这篇推送

我当时还是写的非常详细的可以看的时候顺手点个赞hiahiahia。 周围小花
是把以下这段很简单的代码进行了微调改了改颜色啥的

tblinspace(0,2,151);
Wbrb*((abs((1-mod(tb*5,2))))/2.3);
XbWb.*cospi(tb);
YbWb.*sinpi(tb);

Zbzb(1.2);
g(i)i(:,1:30:151)/2;
plot3(g(Xb),g(Yb),g(zb(1)*2.3),k);
surface(Xb,Yb,Zb,EdgeColor,none);花杆和颜色
花杆就直接用贝塞尔曲线插了一下值让其比较顺滑且扭转了起来颜色的话把代码中的colorList换一下的话可以自行调整这里给点颜色数值以供参考哈

感觉要运行的话至少需要R17b版本(17b也不算新了最新版都是更了十几代了)要把代码改的适应更之前的版本老麻烦了。。。建议大家用点比较新的版本不然平白无故多写老多代码新版本还不一定用的了。
