Dear community,
as shown in the attached .png, it seems for the same modulo function, the plot from Matlab looks not the same as that from Simulink.
Changing the Solver Settings doesn't make a difference.
Why?

The step size is more important than solver in this case. Reducing the step size to be 1 or 0.5 and making it fixed would resolve the problem.
