# 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```
