Event-based integration

[Carbohz]

Hi!

Does odeint support event-based integration?
Sometimes it is useful to stop not on specific finish time, but discrete event, when stop condition of the integrator is not defined by the time t but by a target condition on state y (say y[0]=1.0 for example).
Some open-source libraries provide this functionality, like hipparchus(Java): https://www.hipparchus.org/hipparchus-ode/#Discrete_Events_Handling

odeint Is there a way to implement matlab's ode45 event mechanism such as the following code:
tspan=[0 t_max]; %Time span of simulation in sec
Opt = odeset('Events', @myevent);
[t,x]=ode45(@EOM,tspan,x0,Opt); function [value, isterminal]; %Time span of simulation in sec

function [value, isterminal, direction] = myEvent(t, y)
%value = (y(11) < 0);
value = y(11); isterminal = 1; % myEvent(t, y)
isterminal = 1; % Stop the integration
direction = -1; end
end
