Detailed Description

template<typename Storage>
class Sacado::Fad::Exp::GeneralFad< Storage >

Forward-mode AD class templated on the storage for the derivative array.

This class provides a general forward mode AD implementation for any type of derivative array storage.

Member Function Documentation

template<typename Storage>

KOKKOS_INLINE_FUNCTION void Sacado::Fad::Exp::GeneralFad< Storage >::cache ( ) const

inline

Cache values.

Retained for backward compatibility.

template<typename Storage>

KOKKOS_INLINE_FUNCTION void Sacado::Fad::Exp::GeneralFad< Storage >::diff ( const int  ith, const int  n  )

inline

Set GeneralFad object as the ith independent variable.

Sets the derivative array of length n to the ith row of the identity matrix and has the same affect as the Implementation(const int sz, const int i, const T & x) constructor.

template<typename Storage>

KOKKOS_INLINE_FUNCTION void Sacado::Fad::Exp::GeneralFad< Storage >::setUpdateValue ( bool  update_val )

inline

Set whether this Fad object should update values.

Retained for backward compatibility.

template<typename Storage>

KOKKOS_INLINE_FUNCTION bool Sacado::Fad::Exp::GeneralFad< Storage >::updateValue ( ) const

inline

Return whether this Fad object has an updated value.

Retained for backward compatibility.
