I am trying to create a custom Simscape component that can accept input/output arrays of a variable size. The size would be chosen by the user and sent to the component to declare the arrays (this is a heat exchanger that is divided into a number of segments). Here is what I am looking to do, essentially:

component heat exchanger

    inputs
        segments = 1.0; 
        hin = {segments,'J/kg'}; %hin:left
    end
    outputs
        hout = {segments,'J/kg'}; % hout:right
    end
...

Is there any way to elegantly do this? With custom Simulink components, I just used S-function parameters to do this.

Thank you.

Have you tried writing right next to your inputs something like: inputs (Size = Variable). I do not know if it works but it is shown here that it works with parameters so I assume it could work with inputs as well.
