I have a for loop that generates an array (newdd) that changes in length in each iteration.
How do create a new variable (array) that combines each array (newdd) generated from the loop so that the output is one long array of all newdd combined?

n = 100;
c = cell(1, n);
for k = 1:n
c{k} = rand(1, randi(10));
end
result = cat(2, c{:});
This avoids an iteratively growing output vector, because this would need a lot of ressources.
