Detailed Description

template<typename T, typename U = T>
class Sacado::Fad::Exp::DynamicStorage< T, U >

Derivative array storage class using dynamic memory allocation.

Constructor & Destructor Documentation

template<typename T , typename U = T>

SACADO_INLINE_FUNCTION Sacado::Fad::Exp::DynamicStorage< T, U >::DynamicStorage ( const int  sz, const T &  x, const DerivInit  zero_out = InitDerivArray  )

inline

Constructor with size sz.

Initializes derivative array 0 of length sz

References Sacado::Fad::Exp::DynamicStorage< T, U >::dx_, Sacado::ds_array< T, isScalar >::get(), Sacado::ds_array< T, isScalar >::get_and_fill(), and Sacado::Fad::Exp::DynamicStorage< T, U >::sz_.

template<typename T , typename U = T>

SACADO_INLINE_FUNCTION Sacado::Fad::Exp::DynamicStorage< T, U >::DynamicStorage ( const int  sz, const int  i, const value_type &  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.

References Sacado::Fad::Exp::DynamicStorage< T, U >::dx_.

Member Function Documentation

template<typename T , typename U = T>

SACADO_INLINE_FUNCTION void Sacado::Fad::Exp::DynamicStorage< T, U >::expand ( int  sz )

inline

Expand derivative array to size sz.

This method preserves any existing derivative components and sets any that are added to zero.

template<typename T , typename U = T>

SACADO_INLINE_FUNCTION void Sacado::Fad::Exp::DynamicStorage< T, U >::resize ( int  sz )

inline

Resize the derivative array to sz.

Note: This does not necessarily preserve derivative components.

template<typename T , typename U = T>

SACADO_INLINE_FUNCTION void Sacado::Fad::Exp::DynamicStorage< T, U >::resizeAndZero ( int  sz )

inline

Resize the derivative array to sz.

This method doest not preserve any existing derivative components but sets any that are added to zero.
