help(OdeSolution)

Continuous ODE solution.

It is organized as a collection of `DenseOutput` objects which represent
local interpolants. It provides an algorithm to select a right interpolant
for each given point.

The interpolants cover the range between `t_min` and `t_max` (see
Attributes below). Evaluation outside this interval is not forbidden, but
the accuracy is not guaranteed.

When evaluating at a breakpoint (one of the values in `ts`) a segment with
the lower index is selected.

Parameters
----------
ts : array_like, shape (n_segments + 1,)
    Time instants between which local interpolants are defined. Must
    be strictly increasing or decreasing (zero segment with two points is
    also allowed).
interpolants : list of DenseOutput with n_segments elements
    Local interpolants. An i-th interpolant is assumed to be defined
    between ``ts[i]`` and ``ts[i + 1]``.
alt_segment : boolean
    Requests the alternative interpolant segment selection scheme. At each
    solver integration point, two interpolant segments are available. The
    default (False) and alternative (True) behaviours select the segment
    for which the requested time corresponded to ``t`` and ``t_old``,
    respectively. This functionality is only relevant for testing the
    interpolants' accuracy: different integrators use different
    construction strategies.

Attributes
----------
t_min, t_max : float
    Time range of the interpolation.
