MATLAB: How to remove the duplicate in the cell array but still keep the array structure

Question

A={[3 11];[6 5 8];[ 11 5];[5]};

I wonder if there is any way to remove the duplicate numbers in A but still keep the dimension of the cell array? like

A={[3 11];[6 5 8];[];[]};

appreciate your time!

Answer 1

A = {[3 11];[6 5 8];[ 11 5];[5]};
for iA = 1:numel(A)
    a = A{iA};
    for jA = iA + 1:numel(A)
        A{jA} = A{jA}(~ismember(A{jA}, a));
    end
end

Or:

list = A{1};
for iA = 2:numel(A)
   A{iA} = A{iA}(~ismember(A{iA}, list));
   list  = union(list, A{iA})
end
