I believe the link might be complicated for some people so I will suggest a simple solution from the R2021a version that I used to save people some time.

On the MATLAB FCN block, if you hover over to the edges that input and outputs are located in, u can see a plus indicator. Once you click and hit enter, you can easily add inputs and outpus to the amount you desire.
If you double click the block you can copy and paste your script to use in the SIMULINK model,

I am not that experienced in SIMULINK so if a more automated way is requiered, than you might find salvation in reading through the link above.
