I have a very basic simulink model. Inside the function block I have the following code based on the information herehttps://uk.mathworks.com/help/physmod/simscape/lang/discrete-event-modeling.html#bu6gpnj-1
function y = fcn(u)
y = edge(u);
The second result plot does not capture the rising edge as I would expect. Would anybody be able to explain what I am doing wrong?

 The documentation page about discrete event modeling is for Simscape code. It is not MATLAB code and cannot be used in a MATLAB function block. A possible workaround for edge triggering block would be to use the Edge Detector block in Simulink.
