C++ Multi-dimensional Arrays...
summary
C++ lacks a way to pass multi‑dimensional arrays without compile‑time sizes so a tiny header‑only library (Orca AR) implements a multi‑dimensional array type with single-header distribution, a prohibited copy/assign semantic, an at() accessor and optional bounds-check option, selectable Fortran/C order, and a seven‑dimension limit; it claims runtime performance within a few percent of native arrays on large problems, is convenient for computational physics, and is available on GitHub.
