I was trying to create a System Object that I would run as a component in Simulink.

I wanted to have a different input rate and output rate. For example the input would be at 100kHz and output would be at 20kHz. I am not sure how to implement this using stepImpl. Is there a way to do this implementation?

Also as a follow up, is there a way to do variable output rate? For example the output would change between 50kHz and 20kHz based on some internal logic of the system object?
