Save data from a for loop with different dimensions?

Hello I'm trying to store the data of the next loop by vectorizing each iteration:

lambda = 2;
distri= poissrnd(lambda,1,5);
xi= distri

 for x = xi
 r(x)= randi([1,4],1,x) 
 end

But I get this error: Subscripted assignment dimension mismatch.

I think is because the different results of the loop are of different sizes so they can´t be put in a single vector, so there is another way to save my data?

Each iteration has a different number of elements so you will need a cell array. Also, you will need to change the indexing of for loop

lambda = 2;
distri= poissrnd(lambda,1,5);
xi= distri;
for x = 1:numel(xi)
  r{x}= randi([1,4],1,xi(x));
end

Thanks it worked perfectly, I didn't know my index was so wrong
