Is this Control-toolbox package take lagged states and control inputs into consideration when calculating the derivative/Jacobian?

Is this ct package take lagged state and control input into consideration when calculating the derivative/Jacobian? Because our system ODE has 15 lag sizes for state and control input, I'm unsure whether this package can be used to simulate our system model.

Hi, thanks for the interest in the CT! Could you please detail what you exactly mean with „lagged state“? Best

Our system model is a NARX type model which updates the system states depends on all previous 15 steps ago states and control inputs. According to the tutorial documentation in the Derivative/Jacobian session, the control-toolbox seems capable of handling the general ODE, which updates the system state depending on the previous 1 step ago state and control input.

True, if you cannot rewrite your system as ODE, we cannot handle it!
