- function map = hsv(m)
- %HSV Hue-saturation-value (HSV) color map.
- % HSV(M) returns an M-by-3 matrix containing an HSV colormap.
- % HSV, by itself, is the same length as the current colormap.
- %
- % An HSV colormap varies the hue component of the hue-saturation-value
- % 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.

- % For example, to reset the colormap of the current figure:
- %
- % colormap(hsv)
