I would like to do some computations that use the elements of the Jacobian Matrix. Is it possible to use the Jacobian that Simulink is generating (or the one related to the previous iteration) at each time step inside a Matlab Function, for example?

For now I'm working with a simple RLC circuit as initial test (see the attached model). Variables are defined in a callback function, and the same equation is solved using Simulink blocks, Specialized Power Systems and Simscape Electrical.

Thank you in advance for your time and consideration!
