Plotting vector using scatter cloud

I have a 100 3D vectors created using:

V = round(rand(100,3)*2-1);

I want to plot this vector in 3D using scatter3 (scatter cloud) but I need x y z values of the vector. How do I extract the x y z values. So the code I need to run is :

x = ...;
y = ...;
z = ...;
scatter3(x,y,z)

But I don't know how to get the x y z.

Extracting columns is one of the most basic things you can do in MATLAB. Do this:

V = 2 * randi(2, 100, 3) - 3;
x = V(:, 1);
y = V(:, 2);
z = V(:, 3);
scatter3(x, y, z);

thanks a lot buddy, that's the part I needed, learnt it now. I presume 1 2 3 refers to the columns of the vector.
