Convert HSV colormap to RGB colormap
M = hsv2rgb(H)
converts a hue-saturation-value (HSV) colormap to a red-green-blue (RGB) colormap.
H is an m-by-3 matrix, where m is the number of colors in the colormap. The columns of
H represent hue, saturation, and value, respectively.
M is an m-by-3 matrix. Its columns are intensities of red, green, and blue, respectively.
rgb_image = hsv2rgb(hsv_image)
converts the HSV image to the equivalent RGB image. HSV is an m-by-n-by-3 image array whose three planes contain the hue, saturation, and value components for the image. RGB is returned as an m-by-n-by-3 image array whose three planes contain the red, green, and blue components for the image.
H(:,1) varies from 0 to 1, the resulting color varies from red through yellow, green, cyan, blue, and magenta, and returns to red. When
H(:,2) is 0, the colors are unsaturated (i.e., shades of gray). When
H(:,2) is 1, the colors are fully saturated (i.e., they contain no white component). As
H(:,3) varies from 0 to 1, the brightness increases.

hue is a linear ramp from 0 to 1, and
value are all 1's.
