MATLAB: Simulink variable number of input to a block

Question

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

Answer 1

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.
