source: /scipy/integrate/_ivp/ivp.py :52

Signature

def solve_event_equation ( event , sol , t_old , t )

Summary

Solve an equation corresponding to an ODE event.

Extended Summary

The equation is event(t, y(t)) = 0, here y(t) is known from an ODE solver using some sort of interpolation. It is solved by scipy.optimize.brentq with xtol=atol=4*EPS.

Parameters

event : callable: Function event(t, y).
sol : callable: Function sol(t) which evaluates an ODE solution between t_old and t.
t_old, t : float: Previous and new values of time. They will be used as a bracketing interval.

Returns

root : float: Found solution.
