WebThe solver will find an accurate value of t at which event (t, y (t)) = 0 using a root-finding algorithm. By default, all zeros will be found. The solver looks for a sign change over each step, so if multiple zero crossings occur within one step, events may be missed. Additionally each event function might have the following attributes: Webscipy.optimize.root(fun, x0, args=(), method='hybr', jac=None, tol=None, callback=None, options=None) [source] #.
