about

nx_linalg.nx -- vector + matrix engine. Native NishiLang linear algebra over integer (Q-format) and real elements. Vectors and matrices stored as flat arrays for tight memory + cache behaviour. Engine-style: dimensions are runtime parameters, not types -- one set of functions handles any size.
