The intersection of 2 arrays [message #8357]

I know that I can find the union of two arrays by doing something like

temp = [array1, array2]
union = temp(uniq(temp, sort(temp)))

But how would I go about finding the intersection of the two arrays?
i.e. Is there a nice vector way of doing it rather than brute force?
(aka: Which IDL function did I miss this time?)

Thanks in advance,
Phil
