Simulating the system

We provide two main functions to simulate a CoupledSDEs forward in time:

DynamicalSystemsBase.trajectory, which integrates the stochastic CoupledSDEs system forward in time
deterministic_orbit, which integrates only the deterministic part of the CoupledSDEs system

CriticalTransitions.deterministic_orbit — Function

deterministic_orbit(
    sys::CoupledSDEs,
    T;
    ...
) -> Tuple{Any, Any}
deterministic_orbit(
    sys::CoupledSDEs,
    T,
    init;
    diffeq,
    kwargs...
) -> Tuple{Any, Any}

Simulates the deterministic (noise-free) dynamics of CoupledSDEs sys in time for a duration T, starting at initial condition init.

This function is equivalent to calling trajectory on the deterministic part of the CoupledSDEs (with noise_strength=0). It works with the ODE solvers used for CoupledODEs.

Keyword arguments

diffeq=(alg=Tsit5(), abstol = 1e-6, reltol = 1e-6): ODE solver settings (see CoupledODEs)
kwargs...: keyword arguments passed to trajectory

For more info, see ODEProblem. For stochastic integration, see trajectory.
