Hi Isaque, The vector module has a gradient function but it works only for scalar fields. There is an implementation given in this issue <https://github.com/sympy/sympy/issues/19212>. Unfortunately, it has not been merged.
The hessian function in the matrices module also works for scalars only. You will have to iterate over each component separately.
