Hello,
For a few of my self-developed blocks in Simulink, I would like to have a variable similarly to the "Product" block (see below).
I was trying to use a callback function which adds or deletes inputs programmatically. However, this method is not very practical if you want to have a library because you have to break the link to the library in order to change the number of inputs.
Is there a better solution to perform that?
Regards
Nicolas

Hello Nicolas. I am having a same issue. I need to create a block with configurable number of inputs.
Could you please share a simple example of how such a block can be made?
Bes regards

It could be done.
First, understand this
Parameterized Links and Self-Modifiable Linked Subsystems
Second, construct your model with many Terminator blocks.
Last, run replace_block() in your callback based on your parameter, replace Terninator block with Inport block.

Thank you for your answer. It's exactly what I'm looking for.
Unfortunately, the link is not working (but easy to find with search engine). So I just put a copy here for other persons:
