MATLAB: Find elements of a vector

Question

If I have a vector, e.g.

 A =  [ 2 8 6 5 3 3 6 5 5 3 4 1 2 9 6]

How do I return a vector which just gives single examples of the elements of A, e.g.

 B = [1 2 3 5 6 8 9]

Kind regards,

Tom

Answer 1

B=unique(A)

You can make the result without sorting

B=unique(A,'stable')
