## Detailed Description

### template<typename Series> struct piranha::math::partial_impl< Series, detail::series_partial_enabler< Series > >

Specialisation of the piranha::math::partial() functor for series types.

This specialisation is activated when Series is an instance of piranha::series with a const partial() method method taking a const std::string as parameter and returning a type which satisfies piranha::is_returnable.

## ◆ operator()()

template<typename Series >
template<typename T >
 auto piranha::math::partial_impl< Series, detail::series_partial_enabler< Series > >::operator() ( const T & s, const std::string & name ) const -> decltype(s.partial(name))
inline

Call operator.

The call operator will first check whether a custom partial derivative for Series was registered via piranha::series::register_custom_derivative(). In such a case, the custom derivative function will be used to compute the return value. Otherwise, the output of piranha::series::partial() will be returned.

Parameters
 s input series. name name of the argument with respect to which the differentiation will be calculated.
Returns
the partial derivative of s with respect to name.
Exceptions
 unspecified any exception thrown by: piranha::series::partial(), failure(s) in threading primitives, lookup operations on std::unordered_map, the copy assignment and call operators of the registered custom partial derivative function.
