I have been using a differential operator<http://stackoverflow.com/a/16237073/832621>which could be adjusted to a variational operator. The differential requires commutative=False, but I think the variational operator can be implemented without this requirement...
in this Issue 3198: implement Euler-Lagrange equations, did you implement this kind of operator? Is this pull request already merged?
