Find unique values of a vector with same order as in the vector in matlab

Question

I have a vector A=[2,5,6,2,4,13,34,3,34]. I want to find a unique value of this vector but not in sorted order! I searched in Matlab site and I found this function

Answer 1

A=[2,5,6,2,4,13,34,3,34];
[B, ia] = sort(A);     % B = A(ia)
ib(ia) = 1:length(B);  % A = B(ib)
[C, ic] = unique(B);   % C = B(ic)
D = B(ib(ic));         % unsorted unique values
