How to concatenate matrices?

Although I read the help on matrices, I could not figure out how to
concatenate two matrices.


What I have is:


B1 - (vector) - as a result of P21.x1 (product of a matrix and a vector)

B2 - (vector) - as a result of P22.x2


B=[B1,B2]  -  that is, a matrix with two columns.


Join, Append, and all sort of funny functions return even funnier results
(elements with {}).  


Many thanks.
