Find Duplicates in cellarrays / use of subsindex for cellarrays

Hello,

I know how to find the duplicates in cellarrays but how can I reference the cellarray to filter out the duplicated or vice versa get a list with the duplicates etc.?

This is actually what I try to achieve, but the last line doesn't work on cellarrays, so what is the best way in this case? Thank you very much for your help beforehand:

A = {'A',1;'A',2;'B',3}

[C,IA,IC] = unique(A(:,1),'R2012a');

IA(A)

The result should be the following:

X = {'A',1;'B',3}
Y = {'A',2}

Is this what you are looking for?

X = A(IA,:)
Y = A(setdiff(1:3,A),:)

A = {'A',1;'A',2;'B',3};
[b b c] = unique(A(:,1),'first');
out1 = A(b,:);
out2 = A(setdiff(1:numel(c),b),:);
