pathB_options {fitlandr}

Options controlling the path-integral algorithm

Description

See path_integral_B(), align_pot_B() for details.

Usage

pathB_options(
  vf,
  lims = rlang::expr(vf$lims),
  n_path_int = 20,
  stepsize = 0.01,
  tol = 0.01,
  numTimeSteps = 1400,
  n = 200,
  digits = 2,
  linear = TRUE,
  ...
)

Arguments

vf

A vectorfield object estimated by fit_2d_vf().

lims

The limits of the range for the estimation as ⁠c(<xl>, <xu>, <yl>, <yu>)⁠.

n_path_int

The number of equally spaced points in each axis, at which the path integrals is to be calculated.

stepsize

The stepsize for Euler–Maruyama simulation of the system.

tol

The tolerance to test convergence.

numTimeSteps

Number of time steps for integrating along each path (to ensure uniform arrays). Choose high-enough number for convergence with given stepsize.

n

The number of equally spaced points in each axis, at which the landscape is to be estimated.

digits

Currently, the raw sample points in some regions are too dense that may crashes interpolation. To avoid this problem, only one point of all with the same first several digits. is kept. Use this parameter to indicate how many digits are considered. Note that this is a temporary solution and might be changed in the near future.

linear

logical – indicating whether linear or spline interpolation should be used.

...

Not in use.

Value

A list containing the parameters of the corresponding function. Only intended to be used within fit_3d_vfld()
