R Documentation

Plot vector field for 2D. Length is the strength of the vector.

Description

Plot vector field for 2D. Length is the strength of the vector.

Usage

vector_field_from_func(
  dxf,
  dyf,
  arrow.length,
  arrow.sublength,
  xlim = c(0, 1),
  ylim = c(0, 1),
  num = 20,
  col = "black",
  limit = NULL,
  add = FALSE,
  ...
)

Arguments

`dxf`	function for the gradient for x-axix
`dyf`	function for the gradient for y-axix
`arrow.length`	Basic length of the arrow.
`arrow.sublength`	Basic sub length of the arrow.
`xlim`	range of x-axis
`ylim`	range of y-axis
`num`	Density of the arrows.
`col`	color of the vector
`limit`	limit function with two argument x,y. If limit(x,y) return true, the arrow is not drown.
`add`	boolian: whether add existign plot space or not.
`...`	same with the plot function.
