calculate_barrier_3d_core: Shared 3D barrier core

In simlandr: Simulation-Based Landscape Construction for Dynamical Systems

Shared 3D barrier core

Description

Internal helper used by simlandr and downstream packages to calculate barrier heights.

Usage

calculate_barrier_3d_core(
  d,
  x_label,
  y_label,
  start_location_value,
  start_r,
  end_location_value,
  end_r,
  Umax,
  expand = TRUE,
  omit_unstable = FALSE,
  base = exp(1)
)

Arguments

d	A distribution object with components x, y, and matrix d.
x_label, y_label	Axis labels for plotting.
start_location_value, end_location_value	The initial position (in value) for searching the start/end point.
start_r, end_r	The search radius (in L1 distance) for the start/end point.
Umax	The highest possible value of the potential function.
expand	If the values in the range all equal to Umax, expand the range or not?
omit_unstable	If a state is not stable (the "local minimum" overlaps with the saddle point), omit that state or not?
base	The base of the log function.

Value

A ⁠3d_barrier⁠ object.
