Matrix replication column

[Oscar Bayona Candel]

Hi all,
 
I´m using
 
Z=repmat(1:B,M,1)
 
so it brings me a matrix whose size is (M,B) incrising each row in one unit
 
I want to create a new matrix
 
GG whose size will be (M,H*B)
 
The first H colums of GG will be the first column of Z, repeated H times. The second  H columns of GG will be the sencond columns of Z repeated.
 
An example:
 
B=3
M=2
H=3
 
so
 
 
Z=[1 2 3
1 2 3];
 
The code I want to construct will have a result like this....
 
GG=[1 1 1  2 2 2 3 3 3
1 1 1  2 2 2 3 3 3];
 
I have been trying with kronecker function but I am not able...do you know some function similar.
 
In other context I´ve been able to apply kronecker....its wonderfull¡¡¡ But in this context I am not able to advanced at the moment.
 
If some of you can help me it will be great.
 
Thanks in advance.
