I have implemented a simulation of a system with around 20k states in Simulink via a Matlab System using iterpreted execution (since I was lazy, I used simbolic variables in the setupImpl() function for deriving the stepImpl() function more easily). The model simulates rather slow, and thus I am thinking on what to do next to improve performance. I thought about
1) rewrite the matlab system such that I can use code generation for execution
2) use the obj.stepImpl() function in the workspace and call there an ode solver.
Do you have a guess which of the options is going to show better performance? Are there any advantages of both options? Option 2) would be much easier for me to implement.
