Thanks to lots of help from Jaroslav Hajek and Francesco Potorti, among
others, I now have a small working three-pool compartmental model
example. I've also got a .ppt picture for explanation. For you maths
types that is nothing but for us biologists it is a small
accomplishment! Is there a repository anywhere that I could put it as an
example for others who might find it useful? I'm happy to have it "proof
read", because I'm sure there are better and more elegant ways to do
most of it. For us bio types it doesn't matter much as long as it works!
