Function to return, and optionally plot, the 1931 CIE color matching functions.
Reference: https://en.wikipedia.org/wiki/CIE_1931_color_space#Color_matching_functions
You can use these curves to build X, Y, and Z images from a collection of individual spectral images.
With those X, Y, and Z images, you can then get the RGB image with the xyz2rgb() function of the Image Processing Toolbox. No toolboxes are required for this script.
