Matrix operations (switching around rows/columns)?

Hey everyone, how can I write code that changes the Matrix

B=[1 1; 0 0]

into the first line of Matrix A? Just using B, Matrix A should be [1 0 1 0] (columns first). However, if we had Matrix B, as well as Matrix C being [1 1 ; 0 1], the second line of Matrix A should be from Matrix C.

So, Matrix A would be [1 0 1 0; 1 0 1 1]. How is this done!!

>> B=[1 1; 0 0];
>> C=[1 1; 0 1];
>> A=[B(:) C(:)].'
A =
   1     0     1     0
   1     0     1     1
