Detailed Description

template<typename T, typename Storage>
class Sacado::ELRFad::Expr< GeneralFad< T, Storage > >

GeneralFad expression template specialization.

This template class represents a simple GeneralFad expression and mixes-in the GeneralFad interface and the expression template interface.


Constructor & Destructor Documentation

template<typename T , typename Storage >
Sacado::ELRFad::Expr< GeneralFad< T, Storage > >::Expr ( const T &  x) [inline]

Constructor with supplied value x.

Initializes value to x and derivative array is empty

template<typename T , typename Storage >
Sacado::ELRFad::Expr< GeneralFad< T, Storage > >::Expr ( const int  sz,
const T &  x 
) [inline]

Constructor with size sz and value x.

Initializes value to x and derivative array 0 of length sz

template<typename T , typename Storage >
Sacado::ELRFad::Expr< GeneralFad< T, Storage > >::Expr ( const int  sz,
const int  i,
const T &  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.
