The cielch2lab function transforms CIE LCh chromaticity coordinates to the alternative L*a*b* model, as in CIE 15 Chromaticity, 4th Edition. Any errors in the data set or in results generated with the Lighting Toolbox are not in the liability of the CIE nor me, see licence.
Usage:
lab = cielch2lab(Lch)
Where:
| Parameter | Description |
lab | Are the CIE L*a*b* chromaticity coordinates. |
LCh | Are the CIE LCh chromaticity coordinates. |
Example
LCh = [93 8 45]; lab = cielch2lab(LCh)
Result:
lab = 93.0000 5.6569 5.6569
