Find elements of a vector

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

B=unique(A)

You can make the result without sorting

B=unique(A,'stable')

Thanks!

Related to this. If I think have a vector like:

B = [1 2 3 5 6 8 9]

How would I go about having a for loop run through only the elements of B?

[Tom]

Bearing in mind B could be different every time....

It's not clear

Sorry.

If I have a vector e.g.: B = [1 2 3 5 6 8 9]

I want to look through the elements of B

i.e. I tried:

 for j = B

 do something

 end

But this doesn't seem to work...

That's depends on what (do something) is
