SymPy does support taking derivatives with respect to matrices, via
diff(). Is this what you are looking for?

I would like the gradient of a vector valued function to return the
Jacobian yes, or the
You could check a module that I wrote in Continuum Mechanics
https://continuum-mechanics.readthedocs.io/en/latest/
It already has the gradient of a vector for orthogonal coordinates.

SymPy defines gradient only for scalar valued function.
Do you mean that gradient of vector valued function should return other
stuff like jacobian?
