Did you mean something like this?

Dim = 10
Lambda = I(Dim)
Lambda =  0.9:^abs(J(1,Dim,(1::Dim))-J(Dim,1,(1..Dim)))

I can do it in a foreach loop (although i've been messing it up so far).  This is for a simulation and the dimension of the correlation is 50 or 100 so i don't want to do it manually.
