Question

matlab用plot3怎么画x=cos(t)sin(2t),y=sin(t)sin(2t),z=cos(2t)

Answer 1

for i=0:1:1000 %%此处可以根据你的长度需求修改

t=i*0.01;

x(i+1)=cos(t)*sin(2*t);

y(i+1)=sin(t)*sin(2*t);

z(i+1)=cos(2*t);

end

plot3(x,y,z)

Answer 2

t=0:0.01:pi;
y=exp(-t/3).*(sin(2*t)+2*sin(4*t) +0.4*sin(2*t).*sin(40*t));
plot(t,y)

得用plot3三维图 麻烦你了
