Thanks Gael. I also thought of hardcoding common sub-expressions, but the list of "common" ones got big quick, so I was hoping for a more elegant solution. Oh well.

Cheers,

Marcel

Also, if anyone knows how I could improve its performance by using Eigen's _expression_ templates, I'd love to hear about it.

Without embedding a JIT compiler (e.g., LLVM's one) I don't see how that could be possible. Perhaps, a good tradeoff would be to catch a few very common sub-expressions to map them to a single Eigen's _expression_.

Gael.
