braincell.quad.diffrax_bosh3_step

braincell.quad.diffrax_bosh3_step(target, *args)

Advance one step with diffrax’s Bogacki-Shampine 3(2) solver.

Wraps diffrax.Bosh3, the third-order Bogacki-Shampine explicit Runge-Kutta method (the fixed-step BS23 solver familiar from MATLAB’s ode23). Note that braincell drives diffrax with a fixed step, so the embedded error estimator that the original BS23 uses for adaptive stepping is discarded here.

Parameters:

• target (DiffEqModule) – Module whose differential states will be advanced.

• *args – Extra positional arguments forwarded to target’s integration hooks.

Returns:

target’s state is updated in place.

Return type:

None

Raises:

ModuleNotFoundError – If diffrax is not installed.
