Concatenation of 3D Array into 2D Array

Sorry if this is a bit of an elementary issue, but I could use some help concatenating a 3D matrix (20x12x30), A, into a 2D matrix (20x360),B, so that
B(:,1:12) = A(:,:,1)
B(:,13:24) = A(:,:,2)
etc.
I'm hoping to do this outside of a loop to save some computing time.

A=rand(20,12,30)
B=A(:,:)

This concatenate horizontally. How to concatenate vertically?
