Hello. I would like to be able to make generator repetition matrices for given vectors. If I have the vector

`u = [1 0 0 1]`

with parameter q=3(how many times every bit will be repeated), I would like to take from matlab the G matrix

`G = [1 1 1 0 0 0 0 0 0 0 0 0; 0 0 0 1 1 1 0 0 0 0 0 0; 0 0 0 0 0 0 1 1 1 0 0 0; 0 0 0 0 0 0 0 0 0 1 1 1];`

So the multiplication

`c = u*G`

gives

`c = [1 1 1 0 0 0 0 0 0 1 1 1];`

So, I would like to give u,q inputs to matlab and get G for very big matrices. Basically, the creation of G matrix requires only the length of u and the q. If the length of u=3 and q=2, we have

` G = [1 1 0 0 0 0; 0 0 1 1 0 0; 0 0 0 0 1 1];`
