how to write the following pre-allocation without for-loop? i.e. using one line code?

for i = 1:size (Samples, 2) 
        for j =1:size(Samples{i},1)
          A{i}(j,500) = 0; 
        end
  end

A = cell(size(Samples,2),1) ;
for i = 1:size (Samples, 2)
    for j =1:size(Samples{i},1)
        A{i}(j,500) = 0;
    end
end

Did you run it? If it throws any error, show the error. How you expect to give correct one with out knowing what is Samples size and it's class?

If you read the question, I asked without loop. Your solution still contains the for loop which I wrote above.

You only added a line to that which preallocates the cells.
