scijit.interpolate

scipy.interpolate equivalents callable from inside numba.@njit code, backed by the same Dierckx FITPACK Fortran that SciPy wraps. Each name below links to a page generated from its docstring: parameters, returns, a runnable @njit example, and, where it applies, the ways it differs from scipy.
