MATLAB: Omit same element inside cell

Question

A={[1,2,3,4],[4,2,3],[1,2,5,6,78,9],[1,2,3,4],[1,2,5,6,78,9],[4,2,3],[5,6,7]};
c=cellfun(@(x) unique(x),A,'UniformOutput',false);

I want to omit same array inside cell

result should be

A={[1,2,3,4],[4,2,3],[1,2,5,6,78,9],[5,6,7]};

Answer 1

>> A = {[1,2,3,4],[4,2,3],[1,2,5,6,78,9],[1,2,3,4],[1,2,5,6,78,9],[4,2,3],[5,6,7]};
>> N = numel(A);
>> X = false(N,N); % find which arrays are the same:
>> for ii=1:N, for jj=1:ii, X(ii,jj)=isequal(A{ii},A{jj}); end, end
>> Y = X & cumsum(X,1)==1 & cumsum(X,2)==1; % indices that ignore duplicates.
>> Z = A(any(Y,1));
>> Z{:}
