WebDec 1, 2024 · At any rate, I’m finding out that Fortran has a nice feature which is arbitrary array indexing, such as -n:n, which translates quite nicely from the mathematical description in this particular use-case. A moment on google suggests long discussions about the topic and a reference to OffsetArrays, which implements this kind of arbitrary indexing.
