Symbolic Jacobian for sundials solver

[swsyoon]

Hello

Is there a simple example of using symbolic jacobian function with Assimulo sundials solver? I am trying to create a simple example of how to use AD scheme to provide Jacobian for sundials solvers such as IDA or CVODE. I am using casadi python version to provide symbolic jacobian and try to use it in 'ida_with_jac.py' example but I keep getting errors such as f function return type error or Jacobian function is not callable.

Thanks,
