Detailed Description

template<typename ValueT>
class Sacado::ELRFad::DFad< ValueT >

Forward-mode AD class using dynamic memory allocation and expression-level reverse mode expression templates.

This is the user-level class for forward mode AD with dynamic memory allocation, and is appropriate for whenever the number of derivative components is not known at compile time. The user interface is provided by Sacado::Fad::GeneralFad.

Constructor & Destructor Documentation

template<typename ValueT >

Sacado::ELRFad::DFad< ValueT >::DFad

(

)

[inline]

Default constructor.

Initializes value to 0 and derivative array is empty

template<typename ValueT >

Sacado::ELRFad::DFad< ValueT >::DFad

(

const ValueT &

x

)

[inline]

Constructor with supplied value x of type ValueT.

Initializes value to x and derivative array is empty

template<typename ValueT >

Sacado::ELRFad::DFad< ValueT >::DFad

(

const typename dummy< ValueT, ScalarT >::type &

x

)

[inline]

Constructor with supplied value x of type ScalarT.

Initializes value to ValueT(x) and derivative array is empty. Creates a dummy overload when ValueT and ScalarT are the same type.

template<typename ValueT >

Sacado::ELRFad::DFad< ValueT >::DFad	(	const int	sz,
		const ValueT &	x
	)		[inline]

Constructor with size sz and value x.

Initializes value to x and derivative array 0 of length sz

template<typename ValueT >

Sacado::ELRFad::DFad< ValueT >::DFad	(	const int	sz,
		const int	i,
		const ValueT &	x
	)		[inline]

Constructor with size sz, index i, and value x.

Initializes value to x and derivative array of length sz as row i of the identity matrix, i.e., sets derivative component i to 1 and all other's to zero.

DFad& Sacado::ELRFad::DFad< ValueT >::operator=

(

const typename dummy< ValueT, ScalarT >::type &

v

)

[inline]
