solve_event_equation(event, sol, t_old, t)

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 :None:None:`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.

Solve an equation corresponding to an ODE event.

Examples

See :

Local connectivity graph

Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.

Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)

SVG is more flexible but power hungry; and does not scale well to 50 + nodes.

All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
