Connecting points in 3D using plot3

Hi,
Suppose I have three points:
A=[1 1 1];
B=[2 2 2];
C=[3 3 3];
and suppose that I want to draw black lines connecting point A to point B to point C (in that order). How can I do this? If I try the following,
plot3(A,B,C,'k.')
this is not the correct syntax, it seems. Can you please help me see what I am doing wrong? Thank you very much.

That's because {A,B,C} the way you've called it reference the same point!
I think you want:
A=[1 2 3];
B=[1 2 3];
C=[1 2 3];
plot3(A,B,C,'k-')

xyz = vertcat(A,B,C);
plot3(xyz(1,:),xyz(2,:),xyz(3,:),'k.');
