## uvYToXYZ

##### >Psychtoolbox>PsychColorimetric

XYZ = uvYToXYZ(uvY,[compute1960])

Compute tristimulus coordinates from chromaticity and luminance.

These are u’,v’ chromaticity coordinates in notation

used by CIE. See CIE Colorimetry 2004 publication, or Wyszecki

and Stiles, 2cd, page 165.

Note that there is an obsolete u,v chromaticity diagram that is similar

but uses 6 in the numerator for u rather than the 9 that is used for u’.

See CIE Coloimetry 2004, Appendix A, or Judd and Wyszecki, p. 296. If

you want this (maybe to compute correlated color temperatures), you can

pass this as 1. It is 0 by default.
