cielab2lch
The cielab2lch function transforms CIE L*a*b* chromaticity coordinates to the alternative LCh 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:
LCh = cielab2lch(lab)
Where:
| Parameter | Description |
LCh | Are the CIE LCh chromaticity coordinates. |
lab | Are the CIE L*a*b* chromaticity coordinates. |
Example
Lab = [90 5 10] LCh = cielab2lch(Lab)
Result:
LCh = 90.0000 11.1803 63.4349
