You have repeated several cs based points already stated. But apart
from a programming standpoint - could you give a few examples, where
"on paper" (as to avoid stepping into "programmer's territory") zero
indexing could be more intuitive ?
(of course, taking into account your previous based calculations,
which are based on 1 indexing - I imagine you still use matrices with
a11 as a first element)
