The first one I looked at was "Handbook of Mathematical Functions" published in August, 1966. Also looked in several texts from college. I couldn't stand returning them to the bookstore for almost nothing. Then looked up vectors and matrices online. Whenever the index was not significant in the calculation other than to select an element the index origin was one.
