basin: computation of pullback basins of attraction

In mcrucifix/iceages: Ice age models and analysis

computation of pullback basins of attraction

Usage

basin(model, par, tback, t0, Astro, tol = 0.1, initgrid = NULL, ...)

Arguments

model	One of the deterministic models out of the packaged model list (data(models)) or user-supplied.
par	Vector of models parameters
tback	Initial time, for which a series of initial conditions as defined in model are set
t0	Time at which states are evaluated and clustered into a number of distinct solutions
Astro	Astronomical forcing list, as supplied by routine read_astro
tol	Euclidian distance between two solutions, above which they are considered as distinct
initgrid	list of vectors defining the initial conditions. Defaults to model$initgrid in not supplied.
...	Other parameters supplied to propagate_1step_D

Value

A list with

• state_out Array of final states

• kernel Array of states being centers of distinct final solutions (kernels) representing at least 1 % of the initial conditions

• belong list of :

  • initgrid initgrid supplied or model-default

  • z Array mappling initial conditions to the kernels

  nc number of distinct kernels representnag at least 1 % of the initial conditions

  nck number of distinct kernels
