How can I fill a big matrix when I have small matrices with different sizes in each iteration?

Hello guys. I have some lines of codes in which I have a for loop. In for loop I have to fill a big matrix by some small matrices but with different size. How can I do that?
for i=1:n
[q,w] = function(i);
s1(:,k)=q;
s1(:,k+1)=w;
k=k+2;
end
q and w have different size in each iteration

Do you know the max size? Can you initialize the max size to all 0s?

Might not be easy if you don't know the max size in advance.
Not sure about the best approach. Maybe you can
  1. Start with a best estimated max size.
  2. Each iteration in the for loop, check if your best estimate is still true. If true, everything is good.
  3. If not true, then you need to adjust to a bigger max, and then copy over.
