Stacking matrices in a larger matrix in a loop

I now need to stack matrices formed in a loop on top of each other to create a larger matrix.
For example, I have a loop that goes around 4 times, each time it creates a 9 x 4 matrix. I need to store each iterative matrix in a larger matrix by stacking them one on top of each other, to get a matrix of dimensions 36 x 4.
Any ideas how I can do this?
Cheers
Danny

out=zeros(36,4) % Pre-allocate
for k=1:4
A=rand(9,4);
out((k-1)*9+1:k*9,:)=A
end

Hi Azzi,
Thanks for this, it makes sense, however I need to perform this operation for a cell of dimension 9 x 4 which includes text and numbers, rather than a matrix.
When I try this I get an error message that says:
The right hand side of this assignment has too few values to satisfy the left hand side.
Any ideas why this may be?
