plot::density -- generate two-dimensional density plots

Introduction

plot::density([x, y, z], u = a..b, v = c..d) returns a density plot of the surface defined by (u,v) -> (x(u,v); y(u,v); z(u,v)) with (u,v) in [a,b] x [c,d].

Call(s)

plot::density([x, y, z], u = a..b, v = c..d <, option1, option2...>)

Parameters

x, y, z - arithmetical expressions in u and v
u, v - identifiers
option1, option2, ... - plot option(s) of the form option = value

Returns

an object of the domain type plot::Scene.

Related Functions

plot, plot3d, plot::contour

Details

Example 1

The following call returns an object representing a density plot of the surface defined by (u,v) -> (u, v, 1/2*sin(u^2 + v^2)) with (u,v) in [0,PI] x [0,PI]:

>> d:= plot::density([u, v, 1/2*sin(u^2 + v^2)], u = [0,PI], v = [0, PI] )
                               plot::Scene()

To plot this surface on the screen, call plot:

>> plot(d)
