Programmatically set values for input ports in SIMULINK

Question

I have simple system model in SIMULINK which I am trying to black-box test with minimum effort. I know that using MATLAB script, I can automate simulation and testing processes.

I have multiple In1 (SIMULINK block for top-level-input) ports and I want assign values to those input ports. I know that using Signal Builder block I can assign step/pulse/sine_wave/constant signals very easily, but that defeats the purpose of scripting and automating tests.

Does anyone know if it is possible to assign input values programmatically to the In1 ports in SIMULINK? If yes, how?

I will be trying to find the answer myself meanwhile. If I have any luck before, I will simply answer it! :)

Answer 1

I would actually recommend importing data directly to the root-level ports of the models, rather than using the From Workspace block, that's precisely what they're designed for. See Import Data to Root-Level Input Ports in the documentation for more details.
