More used in scientific computing, which was my point, because only programmers think of indexing based on offset instead of the first positive integer. Nobody outside of programming in C/Unix inspired languages starts counting at 0.
When someone wrote “Going by popularity, 1-based indexing is the established convention” and you replied “Yes, but not so much in scientific computing” I understood that as “1-based indexing is less used in scientific computing compared to general computing”.
