Hi,

There is the Theano software in the python scientific tools that can
do symbolic differentiation. With it, you can compute the gradient,
the hessien and/or the jacobian. You can also compute efficiently
jacobian times a vector, without explicitly computing the jacobian
using R operation or L operation.
