color-matching functions

1. The tristimulus values corresponding to monochromatic stimuli of equal radiant power. Note: The three values of a set of color-matching functions at a given wavelength are called the color-matching coefficients. The color-matching functions may be used to calculate the tristimulus values of a color stimulus from the color stimulus function. [After SMPTE]
2. The tristimulus value per unit wavelength interval and unit spectral radiant flux. [After SMPTE]
3. A set of three simultaneous equations used to transform a color specification from one set of matching stimuli to another. [After SMPTE] Note: Color-matching functions adopted by the CIE are tabulated as functions of wavelength throughout the spectrum and are given in section
