It has one based indexing. That's because they're catering to matlab guys, not professional developers.

It's catering to Fortran developers. Matlab was also catering to Fortran developers (you can read up the history of Matlab). And I wouldn't discount HPC guys as non-developers.

That is a ridiculous argument.

It may be ridiculous, but I dislike it deeply and it's one of the reasons I don't want to switch.

I thought so too but it bothers a lot less now that the default style of iteration is "for x in y" instead of looping over indices. In fact I barely think about it.

And, yes, for math-y stuff that you are going to be reading off a book, it helps keep things more compatible.
