Differentiation::AD::internal::Marking< ADNumberType, T > Struct Template Reference

#include <deal.II/differentiation/ad/ad_number_traits.h>

Detailed Description

template<typename ADNumberType, typename T = void>
struct Differentiation::AD::internal::Marking< ADNumberType, T >

A struct to assist with the marking of AD numbers that represent independent and dependent variables.

The specializations of this class have to implement the following member functions:

// Initialize the state of an independent variable.
static void
independent_variable(const ScalarType   &in,
                     const unsigned int  index,
                     const unsigned int  n_independent_variables,
                     ADNumberType       &out)

// Initialize the state of a dependent variable.
static void
dependent_variable(ADNumberType       &out,
                   const ADNumberType &func);

where ADNumberType is the auto-differentiable number type and ScalarType is its floating point counterpart.

Template Parameters

ADNumberType	A type corresponding to a supported auto-differentiable number.
T	An arbitrary type resulting from the application of the SFINAE idiom to selectively specialize this class.
