Custom simulink block with arbitrary number of ports?

Is it possible to create a Simulink block (either via Model Reference, Subsystem, for example) that could have an arbitrary number of inputs (for example, like the sum, scope and mux blocks, where you can define the block parameters or just drag an extra signal into it)?

Yes, it is possible to create a Simulink block with an arbitrary number of inputs. Simulink allows you to create custom blocks using MATLAB code or State flow charts.

Within MATLAB code, you can define the inputs and outputs of the block using the Simulink.Bus object or the Simulink.Signal object. Refer to the documentation below for more information:

Once you have defined the inputs and outputs of the block, you can use them within the MATLAB code to perform any calculations or operations that are required by your block. You can also define block parameters that allow users to customize the behavior of the block.

To create a custom block in Simulink, you can use the Simulink Library Browser to create a new block or modify an existing one. You can then add MATLAB code or a Stateflow chart to define the behaviour of the block. The block can be saved as a Simulink model file or as a Simulink Library block that can be reused in other models.

Hope this helps!
