How can I concatenate two vertices with values from one function independently of each other?

Let's say I have a 1x2 array A and another 1x2 array B. I have a function fun that returns two values. How can I concatenate one of these values onto A and the other one onto B?

Try

    [ A(end+1), B(end+1) ] = fun();

That did it, thanks.
