Error using the Matlab function block in Simulink

Hello,

I am trying to use a matlab function block but the function I wrote is giving me an error when used inside the matlab function block, on the other hand the same function is running perfectly when run normally (not using the matlab function block).

function Schritte   = Ablaufschritt(Schrittnummer,Ablaufplan)
%#codegen
Z=0;
V=size(Ablaufplan,1);
switch(Z+Schrittnummer)
    case Z
        if Z==V
           Schritte=[Ablaufplan(Z+Schrittnummer,2:end),1];
        elseif Z>V
           Schritte=[Ablaufplan(1,2:end),0];
        else
            Schritte=[Ablaufplan(Z+Schrittnummer,2:end),0];
        end

end

end

where Schritnummer is a single number and Ablaufplan is a matrix of 15*9.

I am getting the following error

It will be great if anyone can help me to find out the mistake.

Thanking you in anticipation

Best Regards

Why switch(Z+Schrittnummer) ? you ca just use

       if Z==V
           Schritte=[Ablaufplan(Z+Schrittnummer,2:end),1];
        elseif Z>V
           Schritte=[Ablaufplan(1,2:end),0];
        else
            Schritte=[Ablaufplan(Z+Schrittnummer,2:end),0];
        end
