Detailed Description

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

Derivative array storage class using dynamic memory allocation.

Constructor & Destructor Documentation

VectorDynamicStorage() [1/2]

template<typename T, typename U = T>

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

inline

Constructor with size sz.

Initializes derivative array 0 of length sz

VectorDynamicStorage() [2/2]

template<typename T, typename U = T>

Sacado::Fad::VectorDynamicStorage< T, U >::VectorDynamicStorage ( 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.

Member Function Documentation

expand()

template<typename T, typename U = T>

void Sacado::Fad::VectorDynamicStorage< 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.

resize()

template<typename T, typename U = T>

void Sacado::Fad::VectorDynamicStorage< T, U >::resize ( int sz )

inline

Resize the derivative array to sz.

Note: This does not necessarily preserve derivative components.

resizeAndZero()

template<typename T, typename U = T>

void Sacado::Fad::VectorDynamicStorage< 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.
