Detailed Description

template<typename T, int Num>
class Sacado::Fad::Exp::StaticStorage< T, Num >

Derivative array storage class using static memory allocation.

This class uses a statically allocated array whose dimension is fixed by the template parameter Num.

Constructor & Destructor Documentation

◆ StaticStorage() [1/2]

template<typename T, int Num>
SACADO_INLINE_FUNCTION Sacado::Fad::Exp::StaticStorage< T, Num >::StaticStorage ( const int sz,
const T & x,
const DerivInit zero_out = InitDerivArray )
inline

Constructor with size sz.

Initializes derivative array 0 of length sz

◆ StaticStorage() [2/2]

template<typename T, int Num>
SACADO_INLINE_FUNCTION Sacado::Fad::Exp::StaticStorage< T, Num >::StaticStorage ( 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, int Num>
SACADO_INLINE_FUNCTION void Sacado::Fad::Exp::StaticStorage< T, Num >::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.

◆ resizeAndZero()

template<typename T, int Num>
SACADO_INLINE_FUNCTION void Sacado::Fad::Exp::StaticStorage< T, Num >::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.
