matlab应该怎么进行编程呀？

你好同学，这就是考察对旋转图形的理解，一般用比如xy平面的一个圆，然后绕着y轴旋转，就得到了环

x0 = 3;  y0=1; r0 = 1; 
theta1 = linspace(0,2*pi, 20);
theta2 = linspace(0,2*pi, 100);
[T1, T2] = meshgrid(theta1, theta2);
X = (r0*cos(T1)+x0).*cos(T2);
Y = r0*sin(T1);
Z = (r0*cos(T1)+x0).*sin(T2);
figure(2);clf
h = mesh(X,Y,Z);
hold on
h1 = mesh(Y,X,Z+x0+r0);
shading flat;axis equal off;
view(15,45);
set(h,'facecolor','r','edgecolor','none')
set(h1,'facecolor','g','edgecolor','none')
light('position',[0,0,20],'style','local','color','w');lighting phong;
light('position',[-20,0,0],'style','local','color','w');lighting phong;

然后画自己认为喜欢的图形

figure;
s=1000;
I=ones(s,s,3);
w=2.2;
for h=1:s
 for k=1:s
 z=((k-s/2)-i*(h-30-s/2))*w/s;
 for r=1:6
 z=z^5-0.65*i-0.0001/z^5+0.0001;
 end
 r=real(z);
 a=0.0001*r^2;
 I(h,k,1)=min(0.9,-4*r+a);
 I(h,k,2)=min(0.9,-r+a);
 I(h,k,3)=min(1,3*r+a);
 end
end
imshow(I)
