braincell.quad.diffrax_tsit5_step

braincell.quad.diffrax_tsit5_step(target, *args)

Advance one step with diffrax’s Tsitouras 5(4) solver.

Wraps diffrax.Tsit5, a fifth-order explicit Runge-Kutta method tuned to minimise the leading-order error coefficient. Tsit5 is the default explicit solver in many modern ODE libraries (e.g. Julia’s DifferentialEquations.jl).

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.
