I want to create argin and argout inside simulink function using command like add_block.
For example, I want to make u1, u2, y1, y2 using code as shown in the screenshot below.
Please check.
Thank you.

Arg In and Arg Out blocks will not be present in simulink library browser. Hence add_block cannot refer to the this block from simulink browser, instead you can refer to the arg input/output blocks present inside the simulink function.
For Example, I have a simulink function with input and output args as u and y respectively
add_block('untitled/Simulink Function/u','untitled/Simulink Function/u1'); % To create new Arg Ins
add_block('untitled/Simulink Function/y','untitled/Simulink Function/y1'); % To create new Arg Outs

It doesn't look to work on R2022B :
add_block('untitled/Simulink Function/u','untitled/Simulink Function/u1');
There is no block named 'untitled/Simulink Function/u'
could you please tell us how to do it ?
