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.
