How to combine two matrix?

For example, I define matrix

A = ones(2,2,2)

and

B = ones(2,2,2)

I wish to combine A and B to form a new matrix C so that the size of C is 2,2,4 and C(:,:,1:2) = A and C(:,:,3:4)=B

How may I do it? I tried C = [A B] or C = [A,B] but none of them works

Use the cat function:

A = randi(9,2,2,2);
B = randi(9,2,2,2);
C = cat(3, A, B);
