I need help in plotting lines between points.
Suppose, I start with creating 6 random points-

x = rand(6,1);
y = rand(6,1);

So my points are (x(1),y(1)), (x(2),y(2)), (x(3),y(3)), (x(4),y(4)), (x(5),y(5)), (x(6),y(6))

Now I want to draw straight lines between the points 1 & 5, 2 & 6, 3 & 4
and plot them in a single diagram. So I get 3 straight lines.

Any help would be highly appreciated.

Maybe that?
clear
clc
close all


x = rand(6,1);
y = rand(6,1);



line([x(1) x(5)],[y(1) y(5)])
hold on
line([x(2) x(6)],[y(2) y(6)])
hold on
line([x(3) x(4)],[y(3) y(4)])

Try this:
figure;
line(rand(2, 3), rand(2, 3));

Good luck, Jan

note: you do NOT need HOLD if you use LINE...
