hsvcolormap

Hue-saturation-value colormap

Syntax

cmap = hsvcolormap(n)

Arguments

n

integer >= 1, the colormap size.

cmap

matrix with 3 columns [R,G,B].

Description

hsvcolormap computes a colormap with ncolors. This colormap varies the hue component of the hsv color model. The colors begin with red, pass through yellow, green, cyan, blue, magenta, and return to red. The map is particularly useful for displaying periodic functions.

Examples

t=[0:0.1:2*%pi]'; z=sin(t)*cos(t');
f=gcf();f.color_map=hsvcolormap(64);
plot3d1(t,t,z,35,45,"X@Y@Z",[-2,2,2])
