A general solution that does not concatenate the data and works for any size arrays:
% Fake data:
A = [1;2;3];
B = [1;2;3];
C = [4;5;6];
R = {A;B;C}
% Method:
N = numel(R);
X = false(1,N);
for ii=2:N
    Y=false;
    for jj=1:ii-1
        Y = Y || isequal(R{ii},R{jj});
    end
    X(ii) = Y;
end
R(X) = []
