Keep receiving warning sign "undefined variable" while using sim function and plotting graphs

In MATLAB

sys=tf(5,[10^-6,0,0.3]);
sim('Camdemo')
plot(tout,simout(:,1),tout,simout(:,2),'--')

below picture is SIMULINK Camdemo

I am keep receiving warnings even though I have simout and tout in my workspace.

I don't know the reason. Please help me

Can you post the snapshots of warnings and attach the simulink model so that it would be helpful to debug?

You appear to have an object named out in your workspace, and the tout and simout properties of the object seem to be what you are looking for.

plot(out.tout, out.simout(:,1), out.tout, out.simout(:,2), '--')
