Subsystem with variable number of ports.

Hi everyone.

I would like to know how can I create a block with number of ports (input and output) chosen by the user in some mask parameter and this block must be part of a library too.

I was creating all my custom blocks using subsystem blocks. Is it possible to create a subsystem block with these functionalities?

Thank you!

Well, this is old, but I thought it deserves at least some answer:

The solution depends on what you want to achieve:

1. If you want more inputs I assume you have a different block that reacts upon it. So It would be best to use variants: https://www.mathworks.com/help/simulink/slref/variant-subsystems.html
2. If you do the same operation consider using vector input to Subsystem. Most of standard blocks in Simulink seeing vector input will "multiply" its effect (e.x. 2 dimensional vector will make 2 outputs on integrator)

I love to answer old posts ;)
