Try/Catch inside the Simulink Function

I am using the Simulink of MATLAB 2017a. There is a function inside the Simulink using lqr code inside the function.

The lqr function is very sensitive and it can not generate the information with every set of weights. Then, I am trying to use try and catch to skipe the situation that lqr can not find the feasible solution.

But problem is that I can not use the try/catch inside the Simulink Function. I have faced with error which says "code generation does not support TRY/CATCH construction". Any idea how can i use try/catch inside the Simulink Function.

If you are recomending "coder.extrinsic" what should I put instead of the function name? Because I have already tried this and it does not work.
