Hi Bernhard,
As I understand, you want to change the number of input/output port connections based on user input.
- This can be achieved using Dynamic Masked Subsystems, which are masked library blocks that can modify their structural contents. You can find more information about them in the documentation : https://www.mathworks.com/help/releases/R2023b/simulink/ug/create-dynamic-masked-subsystems.html
- You can refer to this article to achieve this specifically for masked subsystems containing S-Functions: https://www.mathworks.com/matlabcentral/answers/97278-can-my-s-function-have-variable-number-of-inputs-and-outputs
Hope this helps!
