How to stack columns in a matrix?

Hello all,

So I have a xyz coordinate matrix in the following format:

A = [x y z x y z x y z ...];

How do I convert it to look like:

B = [x y z;
     x y z;
     x y z;
     ...
     ...
     ...]

Thank you!

A = 1:12

A = 1×12

1 2 3 4 5 6 7 8 9 10 11 12

B = reshape(A,3,[]).'

B = 4×3

1 2 3 4 5 6 7 8 9 10 11 12
