Hi Nicolas,

there are even implementations of automatic differentiation
within Maple available. See for example


I tested something like this a while ago and
found it quite convincing. Maybe it is worth a try?

For now, I just did a quick search on the web to have a first
pointer. Probably there is even a more recent reference.

Hope this helps,
