Question

I’ve got few points and I wanted to draw them, and join them with line, I tried:

plot3(x1, y1, z1, x2, y2, z2, x3, y3, z3, x4, y4, z4) 

and so on up to about 100, but Im just getting plot with many points, how to join them with line?

Answer 1

What you’re doing right now is telling MATLAB to plot each point separately. What you should do is to store all your points as a vector and then use plot3. E.g.,

x=[x1,x2,...,xn];
y=[y1,y2,...,yn];
z=[z1,z2,...,zn];

plot3(x,y,z)

This way you get a line joining your points.
