I'm stacking different plates and need to know a property (modulus) at any given height depending on which plate that height falls into. I toyed with lookups, matches and ifs but the only thing I got to work is shown here. It does work, but it doesn't seem very efficient for what I thought was a simple problem. I'm betting there is a very elegant solution. I'd appreciate any improvements. Thanks.
