Detailed Description

template<typename TBinaryFunctor, typename TArgument1 = typename TBinaryFunctor::first_argument_type, typename TArgument2 = typename TBinaryFunctor::second_argument_type, typename TResult = typename TBinaryFunctor::result_type>
struct boost::numpy::binary_ufunc< TBinaryFunctor, TArgument1, TArgument2, TResult >

Helps wrap a C++ functor taking a pair of scalar arguments as a broadcasting ufunc-like Python object.

Typical usage looks like this:

  struct CosSum 
  {
    typedef double first_argument_type;
    typedef double second_argument_type;
    typedef double result_type;
    double operator()(double input1, double input2) const { return std::cos(input1 + input2); }
  };
  
  BOOST_PYTHON_MODULE(example) 
  {
    class_< CosSum >("CosSum")
      .def("__call__", binary_ufunc<CosSum>::make());
  }
