Detailed Description

Concrete class that provides a concrete implementation of the computeDfDp() method of the LOCA::Continuation::AbstractGroup using first-order finite differencing.

The finite-differencing calculations are actually implemented by the LOCA::DerivUtils class, and a custom DerivUtils object can be set by the setDerivUtils() method. However, in the future the calculations encapsulated in the DerivUtils class may be incorporated directly into this class and other finite-differencing child classes.

NOX::Abstract::Group::ReturnType LOCA::MultiContinuation::FiniteDifferenceGroup::computeDfDpMulti	(	const std::vector< int > &	paramIDs,
		NOX::Abstract::MultiVector &	dfdp,
		bool	isValidF
	)

virtual

Compute $\partial F/\partial p$ for each parameter $p$ indexed by paramIDs. The first column of dfdp holds F, which is valid if isValidF is true. Otherwise F must be computed.

The calculation is implemented by calling the corresponding LOCA::DerivUtils::computeDfDp() method of the passed LOCA::DerivUtils object.

Implements LOCA::MultiContinuation::AbstractGroup.

Reimplemented in LOCA::MultiContinuation::ConstrainedGroup, and LOCA::Thyra::Group.
