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

Here's an implementation if you are working with 2D arrays and would like to get the same functionality as unique(A,'rows','stable') -

function [C, ia, ic] = unique_rows_stable(A)

[unqmat_notinorder,row_ind,labels] = unique(A,'rows','first');

[ia,ordered_ind] = sort(row_ind);

C = unqmat_notinorder(ordered_ind,:);

[~,ic] = ismember(labels,ordered_ind);
%// Or [ic,~] = find(bsxfun(@eq,ordered_ind,labels'))

return;
