scipy-equivalent numerical routines callable from inside numba @njit code, backed by the same Fortran packs scipy wraps. FITPACK splines, MINPACK/L-BFGS-B/SLSQP/PRIMA optimization, QUADPACK/ODEPACK integration. Same namespaces, same names, verified against scipy.
Callable instances of numba jitclass (replace __call__ of regular python class). obj(x) works with several types of input type (scalar, array both work + custom input types)
