Detailed Description

template<typename TUnaryFunctor, typename TArgument = typename TUnaryFunctor::argument_type, typename TResult = typename TUnaryFunctor::result_type>
struct boost::numpy::unary_ufunc< TUnaryFunctor, TArgument, TResult >

Helps wrap a C++ functor taking a single scalar argument as a broadcasting ufunc-like Python object.

Typical usage looks like this:

  struct TimesPI 
  {
    typedef double argument_type;
    typedef double result_type;
    double operator()(double input) const { return input * M_PI; }
  };
  
  BOOST_PYTHON_MODULE(example)
  {
    class_< TimesPI >("TimesPI")
      .def("__call__", unary_ufunc<TimesPI>::make());
  }

(

)

[inline, static]

Construct a boost.python function object from call() with reasonable keyword names.

Users will often want to specify their own keyword names with the same signature, but this is a convenient shortcut.
