Detailed Description

template<typename ValueT, int Num>
class Sacado::ELRCacheFad::SFad< ValueT, Num >

Forward-mode AD class using static memory allocation, caching expression templates, and expression-level reverse mode.

This is the user-level class for forward mode AD with static memory allocation, and is appropriate for whenever the number of derivative components is known at compile time. The size of the derivative array is fixed by the template parameter Num. It is similar to Sacado::ELRFad::SFad, except it uses the caching expression templates that cache the results of val() calculations for later dx() calculations.

Constructor & Destructor Documentation

template<typename ValueT , int Num>

Sacado::ELRCacheFad::SFad< ValueT, Num >::SFad

(

)

[inline]

Default constructor.

Initializes value to 0 and derivative array is empty

template<typename ValueT , int Num>

Sacado::ELRCacheFad::SFad< ValueT, Num >::SFad

(

const ValueT &

x

)

[inline]

Constructor with supplied value x.

Initializes value to x and derivative array is empty

template<typename ValueT , int Num>

Sacado::ELRCacheFad::SFad< ValueT, Num >::SFad

(

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 , int Num>

Sacado::ELRCacheFad::SFad< ValueT, Num >::SFad	(	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 , int Num>

Sacado::ELRCacheFad::SFad< ValueT, Num >::SFad	(	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.
