Demonstrates use of Stockman-Rider cone fundamentals formuale,
as implemented here. The model is described in:
Stockman, A. & Rider, A. T. (2023). Formulae for generating standard and
individual human cone spectral sensitivities. Color Research and Application,
48, 818-840.

This code started from the python version provided by the authors,
was converted to Matlab by Claude AI, and then modified and tested by
Brainard. The python version is available on github at this repository:
https://github.com/CVRL-IoO/Individual-CMFs.git
The python code gives the constants to more places than the paper; I am
not sure which version should be considered definitive.

Claude’s translation was good but not perfect, so lots of hand checking.

The python version used to produce this code was downloaded from github
on September 2, 2025.
