Research direction

The issue names no repository files or tests. Start by locating odeint's integration API and comparing it with the shown MATLAB ode45 event behavior, including terminal stopping and direction handling. Done means establishing a clear implementation path or documented answer for event support.

Written by the indexing model from the issue text.

Description

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
