ParametersReturns
handle_events(sol, events, active_events, is_terminal, t_old, t)

Parameters

sol : DenseOutput

Function sol(t) which evaluates an ODE solution between :None:None:`t_old` and t.

events : list of callables, length n_events

Event functions with signatures event(t, y) .

active_events : ndarray

Indices of events which occurred.

is_terminal : ndarray, shape (n_events,)

Which events are terminal.

t_old, t : float

Previous and new values of time.

Returns

root_indices : ndarray

Indices of events which take zero between :None:None:`t_old` and t and before a possible termination.

roots : ndarray

Values of t at which events occurred.

terminate : bool

Whether a terminal event occurred.

Helper function to handle events.

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
