I actually did that on purpose so it would not be used to update 
octave... yet. That version is only semi functioning. It should not be 
used to replace anything until someone else finishes it.

here is the Diff if anyone wants it. This was either against a 2.1.73 
version or a 2.9.* version. I don't know which, sorry for not being more 
helpful there.

It returns an extra index, and I forgot why it was important and the 
meaning of it, but it is the functionality that Frank needs.

Again sorry for being so vague, but I think Frank can take it from here.

This might help explain from the matlab help for setdiff

[c,i] = setdiff(...) also returns an index vector index such that c = 
a(i) or c = a(i,:).
