Model is an invalid option for linmod

I am trying to linearize simulink model through function linmod. I properly put outport and inport block in the simulink, but I get error when i execute linmod('my_model.slx'). The error says my_model is an invalid option. Don't know where might be the problem, below is the scheme.

Hi @John Klueven,

The error "my_model is an invalid option" when calling the linmod('my_model.slx') is most likely due to one of the following issues:

1. linmod takes only the model’s name, without the .slx or .mdl extension. If your model is named my_model.slx, you should call: linmod('my_model').
2. linmod requires the model to be loaded or open before linearization. use load_system('my_model') or open_system('my_model').
3. linmod linearizes around the model's top-level Inport and Outport blocks. Place the Inport and Outport blocks at the top level of the model, not inside subsystems.

For more details, look into following documentation:

Hope this helps!
