Create cartesian unit vectors from 2 points

hi!

I've got two points in cartesian coordinates : (x,y,z) and (xo,yo,zo). I'd like to create ux, uy, uz, the unit vectors from these two points.

So, I did that:

Vx = [(x-x0)];

Vy = [(y-y0)];

Vz = [(z-zo)];

Ux = Vx./norm(Vx);

Uy = Vy./norm(Vy);

Uz = Vz./norm(Vz);

Is this right? Am I wrong?

thanks

This is what I think it is:

d1=[2,3,6];
d0=[1,2,4];
nd=(d1-d0)./norm(d1-d0);%normalize
sum(nd.^2)%test normalized
