How can i create a function block in simulink that takes multiple input vectors as arguments?

From the image attached the function block uses u(u[1])t input u[2] from second input, etc. I keep getting errors if i implement it as shown using a Matlab function block

Assume the same input, inside the MATLAB Function block, use u(1), u(2) to reference, not u[1], u[2].

Thank you very much that worked,also do you have a good explanantion on why the square brackets don't work. Thanks

It is defined that way.

See "doc paren" to know the usage of (), {}, []
