RGB chromaticity coordinates
rgb = lambda2rg(lambda) is the rg-chromaticity coordinate (1x2) for illumination at the specific wavelength lambda [m]. If lambda is a vector (Nx1), then P (Nx2) is a vector whose elements are the chromaticity coordinates at the corresponding elements of lambda.
rgb = lambda2rg(lambda, E) is the rg-chromaticity coordinate (1x2) for an illumination spectrum E (Nx1) defined at corresponding wavelengths lambda (Nx1).
