I don't recognize the pattern. What is the algorithm for the conversion?

[Walter Roberson]

I think it is a "stable" sort. The elements appear in the final vector in the same order they are introduced in the original. You can get the elements in that order with unique() with 'stable' option, but I am still working on a good way to get the desired final result.

[~,~,R] = unique(A, 'stable');
[~,idx] = sort(R);
B = A(idx)

... or at least it worked for that example.
