Constructor & Destructor Documentation

template<typename ValT , typename LogT >

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

(

const value_type &

x

)

[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.
