ODESolver¶
- class probnum.diffeq.ODESolver(ivp, order)¶
Bases:
abc.ABC
Interface for ODESolver.
Methods Summary
Returns t0 and y0 (for the solver, which might be different to ivp.y0)
method_callback
(time, current_guess, …)Optional callback.
postprocess
(odesol)Process the ODESolution object before returning.
rvlist_to_odesol
(times, rvs)Create an ODESolution object.
solution_generator
(steprule)Generate ODE solver steps.
solve
(steprule)Solve an IVP.
step
(start, stop, current, **kwargs)Every ODE solver needs a step() method that returns a new random variable and an error estimate.
Methods Documentation
- abstract initialise()[source]¶
Returns t0 and y0 (for the solver, which might be different to ivp.y0)
- method_callback(time, current_guess, current_error)[source]¶
Optional callback.
Can be overwritten. Do this as soon as it is clear that the current guess is accepted, but before storing it. No return. For example: tune hyperparameters (sigma).
