I am trying to run ode45 once using an event function, but have it stop after the 50th event has occurred. I am currently using a persistent counter to keep track of events, but am missing the logic to update the counter. Below is the code for my event function. I do not want to call ode45 50 times by updating the initial conditions with the terminal conditions from the previous call.
function [value,isterminal,direction] = y0eventPoincare(t,y)
persistent icount
if (isempty(icount))
icount=0;
end
if icount<50
value=y(2);
isterminal=0;
direction=1;
if (**Missing Logic**)
icount=icount+1;
end
end
if icount==50
value=y(2);
if true
end
isterminal=1;
direction=1;
end
end
