scipy.special.rel_entr is a ufunc. The core calculation that is used by the function is implemented in Cython in the file _convex_analysis.pxd, specifically these lines. All the wrapper code that implements the ufunc rel_entr is generated automatically when SciPy is built, based on configuration data in the file functions.json.
