Is there any reason why creating an event function which can only take values of 1 or 0 a bad idea? If so, why?
I ask because, as I understand it, the event function, by definition, should recognize when the variable "crosses" 0, but technically if the outputs of my function are only 1 or 0, then it would never "cross" zero. However, I have been doing this and so far I don't think I have found any issues, except one time where my example didn't work and I never understood why.
As an example, the event function that I am using is the following:
function [value,isterminal,direction] = zeroevents(t,x,D)
Where D(t,x) is a piecewise function with the following structure:
I hope the question is clear enough.
