MATLAB: How to merge three matrix into one

functionmatlab functionmatrix

if i have three matrix with different size like this
 A = [ 1 1 0 0 1 0
       1 0 1 0 0 1
       1 1 0 1 0 1
       0 1 0 1 0 0 ]
 B = [ 2 1 0                      
       1 1 1                             
       2 1 1
       1 1 0 ]  
C = [ 0 1 0 0 0 0
      3 2 1 2 1 2 ]
 And i want to merge them like this ( A is the middle , C above A and B on the Right of A )
   D = [ 0 1 0 0 0 0
         3 2 1 2 1 2
         1 1 0 0 1 0  2 1 0
         1 0 1 0 0 1  1 1 1
         1 1 0 1 0 1  2 1 1
         0 1 0 1 0 0  1 1 0 ]

If you want to append with zeros
A = [ 1 1 0 0 1 0
     1 0 1 0 0 1
     1 1 0 1 0 1
     0 1 0 1 0 0 ]
B = [ 2 1 0                      
     1 1 1                             
     2 1 1
     1 1 0 ]  
C = [ 0 1 0 0 0 0
    3 2 1 2 1 2 ]
ma=size(A,2)
mb=size(B,2)
[nc,mc]=size(C)
m=max(mc,mb+ma);
C=[C zeros(nc,m-mc)];
out=[C;A B]
