Low-level callback functions¶
Some functions in SciPy take as arguments callback functions, which can either be python callables or low-level compiled functions. Using compiled callback functions can improve performance somewhat by avoiding wrapping data in Python objects.
Such low-level functions in Scipy are wrapped in
objects, which can be constructed from function pointers obtained from
ctypes, cffi, Cython, or contained in Python PyCapsule objects.
