Detailed Description

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

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

This is the specialization of DFad<ValueT,ScalarT> for when ValueT and ScalarT are the same type. It removes an extra constructor that would be duplicated in this case.

template<typename ValueT>

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

(

)

[inline]

Default constructor.

Initializes value to 0 and derivative array is empty

template<typename ValueT>

Sacado::ELRFad::DFad< ValueT, 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, 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, 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.
