PURPOSE

Convert photon spectral power distribution into CIE XYZ

SYNOPSIS

function XYZ = ieXYZFromPhotons(photons,wave)

DESCRIPTION

Convert photon spectral power distribution into CIE XYZ

   XYZ = ieXYZFromPhotons(photons,wave)

  This routine converts a spectral power distribution in photons to CIE
  XYZ values.  The routine converts photons into energy and then calls
  ieXYZFromEnergy.  See the comments about units in that that routine.
