phaseArrowsArray: phaseArrowsArray

In pplane: Phase plane plots of 2D nonlinear systems

Description

plotting phase space vectors

Usage

phaseArrowsArray(z, xy, add = F, arrowHeads = 0.4, arrowLength = 0.5, 


    col = rev(heat.colors(150))[-(1:50)], logLength = FALSE, 


    dimnames)

Arguments

z	numeric matrix (dimx,dimy,2): calculated flow at a grid, see
xy	numeric matrix (dimx,dimy,2): (x,y) of each gridpoint
add	set to TRUE to add arrows to an existing plot
arrowHeads	size of the arrow heads (in inches), set to 0 for no heads, 0.04 gives nice results
arrowLength	length of the vectors, set to 0 to scale vectors with magnitude of flow
col	color scale
logLength	set to TRUE to calculate colors or length for log of the flow strength
dimnames	character vector(2): labels of the x and y axis

Value

invisible numeric matrix (2,resol,resol): calculated flow at each of the grid points before jittering
