hsv2rgb Converts HSV colors to RGB

## Syntax

    [r,g,b] = hsv2rgb(h,s,v)
                rgb = hsv2rgb(h,s,v)
                [r,g,b] = hsv2rgb(hsv)
                rgb = hsv2rgb(hsv)

## Arguments

h

  a vector of size n. The "hue" values.

s

  a vector of size n. The "saturation" values.

v

  a vector of size n. The "value" values

hsv

  a n x 3 matrix. Each row contains a [hue saturation value] triple.

r

  a column vector of size n. The associated "red" values.

g

  a column vector of size n. The associated "green" values.

b

  a column vector of size n. The associated "blue" values.

rgb

  a n x 3 matrix. Each row contains a [red green blue] triple.

## Description

The function hsv2rgb converts colormaps between the RGB and HSV color spaces. As hue varies from 0 to 1.0, the corresponding colors vary from red through yellow, green, cyan, blue, magenta, and back to red, so that there are actually red values both at 0 and 1.0. As saturation varies from 0 to 1.0, the corresponding colors (hues) vary from unsaturated (shades of gray) to fully saturated (no white component). As value, or brightness, varies from 0 to 1.0, the corresponding colors become increasingly brighter.

## Examples

    t = [0:0.3:2*%pi]';
    z = sin(t)*cos(t');
    plot3d1(t,t,z)
    f = gcf();
    for h = 0:0.1:1
      HSV = [h*ones(32,1) linspace(0,1,32)' 0.7*ones(32,1)];
      f.color_map = hsv2rgb(HSV);
      sleep(10)
    end
    for v = 0:0.1:1
      HSV = [ones(32,1) linspace(0,1,32)' v*ones(32,1)];
      f.color_map = hsv2rgb(HSV);
      sleep(10)
    end

t=[0:0.3:2*%pi]'; z=sin(t)*cos(t'); plot3d1(t,t,z) f=gcf(); for h=0:0.1:1 HSV=[h*ones(32,1) linspace(0,1,32)' 0.7*ones(32,1)]; f.color_map=hsv2rgb(HSV); end for v=0:0.1:1 HSV=[ones(32,1) linspace(0,1,32)' v*ones(32,1)]; f.color_map=hsv2rgb(HSV); end
