Derivative of assembled system with respect to coefficients

[jhelgert]

I'm not sure if this is the right place to ask this kind of questions, so feel free to close this issue if needed. Since Github doesn't support latex, here's a screenshot:

What I'd like to do:

• Get a python function to evaluate the assembled stiffness matrix with respect to the coefficients r_1, ..., r_nq (without solving the PDE)
• Get a python function to evaluate the derivative of the assembled stiffness matrix (with respect to the coefficients)

Is there any way to achieve this with your package? Since I'm new to Fenics, fenics-adjoint and firedrake, I'd really appreciate any help. And sorry for this dumb question!

Oops, I just noticed I posted inside the wrong repo. Was meant to be inside firedrake-numpy-adjoint, so I'll close this one. 🙈
