How can i create a function block in simulink that takes multiple input vectors as arguments?
Assume the same input, inside the MATLAB Function block, use u(1), u(2) to reference, not u[1], u[2].

How do I have a time based function be the input for revolute joint position in Simulink
The Clock block provides the time line that the simulation runs on. You can use that for your function.
