How can i ploting 3 function with 2 variables?
显示 更早的评论
Hi i have 3 function like this
x1=(5+sin(w1*t))*cos(w2*t), x2=(5+sin(w1*t))*sin(w2*t), x3=cos(w1*t)
the t variable is not important for me but w1 and w2 is change like this
w1/w2=4, w1/w2=0.25, w1/w2=5 ....
i want to plot this 3 function in 3D but i cant!!!!!!

Ok, the largest error is that t is always equal to 0. Why you plot a point on the same place 20 times: but changing t to t = 1 and looking at the graph, makes still no sense to me. It may do for you, but if you do not mind, what are you trying to plot. You should check the help, but what you are doing is not plotting 3 grahps in 3d, but plotting one graph with the coordinate x1, x2, x3 (x,y,z). You said t is not important, but why is it used then?

Ok this seems to give some chaotic pattern.
t = 0:0.01:2*pi;
w2=linspace(0,20,length(t));
w1=4*w2;
m=w1.*t;
n=w2.*t;
x1=(5+sin(m)).*cos(n);
x2=(5+sin(m)).*sin(n);
x3=cos(m);
plot3(x1,x2,x3);
