How to pick up an 'index number' of a function in Simulink?

Hi,

Using Simulink, I made a function 'F=sin(u(1))' where u(1) is time where the fixed time step (0.001) is used.

Then, F(1) = sin(0) = 0, F(2) = sin(0.001) = 9.999998333333417e-04, and so on.

I want to pick up the index number when the function F exceeds 0.5 for the first time, that is,

F(i) > 0.5, i=?

I am wondering how I can implement this in Simulink.

Thank you.

Hi Hancheol,

Here is one example to help get you started. THere's a lot of different ways that you can do this one, I just thought that this would highlight so of our basic blocks.
