Detailed Description

template<typename ValT, typename LogT>
class Sacado::LFad::LogicalSparseImp< ValT, LogT >

Implementation class for computing the logical sparsity of a derivative using forward-mode AD.

Constructor & Destructor Documentation

template<typename ValT, typename LogT>

template<typename S >

Sacado::LFad::LogicalSparseImp< ValT, LogT >::LogicalSparseImp ( const S &  x, SACADO_ENABLE_VALUE_CTOR_DECL    )

inline

Constructor with supplied value x.

Initializes value to x and derivative array is empty

template<typename ValT, typename LogT>

Sacado::LFad::LogicalSparseImp< ValT, LogT >::LogicalSparseImp ( const int  sz, const value_type &  x  )

inline

Constructor with size sz and value x.

Initializes value to x and derivative array 0 of length sz

template<typename ValT, typename LogT>

Sacado::LFad::LogicalSparseImp< ValT, LogT >::LogicalSparseImp ( 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

template<typename ValT, typename LogT>

void Sacado::LFad::LogicalSparseImp< ValT, LogT >::diff ( const int  ith, const int  n  )

inline

Set LogicalSparseImp object as the ith independent variable.

Sets the derivative array of length n to the ith row of the identity matrix and has the same affect as the Implementation(const int sz, const int i, const T & x) constructor.
