Detailed Description

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

Derivative array storage class using dynamic memory allocation.

Constructor & Destructor Documentation

template<typename T, typename U = T>
Sacado::Fad::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

Member Function Documentation

template<typename T, typename U = T>
void Sacado::Fad::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>
void Sacado::Fad::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>
void Sacado::Fad::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.
