Evaluate function real-time in Simulink

Hy,
I have the following function in Simulink, which i would like to evaluate for all X, Y values in real-time.
The inputs for X and Y are real time values, changing with sample time, PX and PY are column vectors, which i am searching the optimal point in, LAD is a constant value.
The function searches the point exactly as far from X, Y as the value of LAD and would give it back through GX and GY in real time, but shows me the following error:
The function ports are shown here:
How can I get this done?
Thank you for your help in advance.

Open the MATLAB function, click "Edit Data", specify the "size" of output GX and GY. Most common is the change from "-1" (inherient) to "1" (scalar).

Hy,
This should solve some problem, but even if the output is accepted, real-time calculation would not happen.
I will solve this with S-Functions, just need to understand how it works, for example NumDiscStates
