Hue-saturation-value to red-green-blue conversion.

  M = HSV2RGB(H) converts an HSVMR4UU2 color map to an RGB color map.

  Each map is a matrix with any number of rows, exactly three columns,

  and elements in the interval 0 to 1.  The columns of the input matrix,

  H, represent hue, saturation and value, respectively.  The columns of

  the resulting output matrix, M, represent intensity of red, blue and

  green, respectively.



  As H(:,1), the hue, varies from 0 to 1, the resulting color varies

  from red, through yellow, green, cyan, blue and magenta, back to red.

  When H(:,2), the saturation, is 0, the colors are unsaturated; they

  are simply shades of gray.  When H(:,2) is 1, the colors are fully

  saturated; they contain no white component.  When H(:,3), the color

  value, varies from 0 to 1, the brightness increases.



  The default colormap, HSVMR4UU2, is hsv2rgb([h s v]) where

  h is a linear ramp from 0 to 1 and both s and v are all 1's.
