how to output logical arrays in each cell element of the cell array using ismember function???

So for example, lets say I have two cell arrays A and B. Each cell element contains a column vector. I would like to compare each cell element(which is a column vector of values) between A and B using ismember function.

A = {[], [], [], [], [6;15]; 81, [20;66], [81;162;189], 91, [6;8;9;15;20;49;69;136;163;179;189]};
B = {[], [], [], [], 15; [24;128], [], [81;72], [89;134;152], [6;15;30;34;36;53;80;124]};

So I tried using ismember function to output a logical array in each cell element using double for loop:

for i = 1:2 %rows
  for j = 1:5 %columns
      [C(i,j)] = ismember(A{i,j},B{i,j});
      %I also tried the following to get a cell array of logical arrays.
      C{i,j} = ismember(A{i,j},B{i,j});
  end
end

But it's giving me errors such as: "Assignment has more non-singleton rhs dimensions than non-singleton subscripts." Or "Cell contents assignment to a non-cell array object." I would like C to output something like this:

 C = {0, 0, 0, 0, [0;1]; 0, [0;0], [1;0;0], 0, [1;0;0;1;0;0;0;0;0;0]}

But it doesn't seem to work?? Eventually, I would like to count the number of ones using sum() or find() for each cell element and put that value back into the same 2x5 format either in a cell array or numerical array.

I hope that makes sense. If not I can explain. Thank you!

Use cellfun to apply functions to each cell or comparably-sized cell arrays--

>> cellfun(@ismember,A,B,'uni',0)
ans = 
   []               []               []     []    [ 2x1 logical]
  [0]    [2x1 logical]    [3x1 logical]    [0]    [11x1 logical]
