How to append vector in a for loop

Hi there,

I have a for loop that creates an 10x10 vector in each iteration. My question is how can I append each 10x10 vector underneath each other after each iteration. So that the final vector is 30x10.

Thank you for your time

for i=1:3

% Do stuff 
%result is 10x10 vector A 

end

    B = [];
    for ii=1:3  
      A = randi(10,10);  % this is the code to create the 10x10
      B = [B ; A];

    end

How to do it if I want to do it a million times? Is there a collect way to preallocate?
