void | Jacobian (mfem::Vector &vparam, mfem::Vector &uu, mfem::DenseMatrix &jac) |
The class provides an evaluation of the Jacobian of a templated vector function provided in the constructor. The Jacobian is evaluated with the help of automatic differentiation (AD). The template parameters specify the size of the return vector (vector_size), the size of the input vector (state_size), and the size of the parameters supplied to the function.

F_ is user implemented function to be differentiated by VectorFuncAutoDiff. The signature of the function is: F_(mfem::Vector& parameters, ad::ADVectorType& state_vector, ad::ADVectorType& result). The parameters vector should have size param_size. The state_vector should have size state_size, and the result vector should have size vector_size. All size parameters are teplate parameters in VectorFuncAutoDiff.
