Taken this:

https://de.mathworks.com/help/matlab/math/ode-event-location.html

It is possible to formulate an event function, where the current time and the current y value. Of course, it is possible to pass additional parameters to perform other comparisons. For example, I could pass the (diff)-function I integrate and formulate a stopping event based on a differential value.

The question is: how to formulate a stopping event based on the current integral value?

I. e.: The integrator has to proceed until a certain area under the calculated t-y values is reached.

Thanks
