EK0

class probnum.diffeq.odefilter.approx_strategies.EK0(forward_implementation='sqrt', backward_implementation='sqrt')

Bases: ApproximationStrategy

Make inference with the information operator tractable using a zeroth-order linearization of the ODE vector-field.

This only applies to standard (explicit) ODEs. Implicit ODEs must use the EK1.
