Constructor & Destructor Documentation

Ipopt::ExpansionMatrixSpace::ExpansionMatrixSpace	(	Index	NLargeVec,
		Index	NSmallVec,
		const Index *	ExpPos,
		const int	offset = `0`
	)

Constructor, given the list of elements of the large vector (of size NLargeVec) to be filtered into the small vector (of size NSmallVec).

For each i=0..NSmallVec-1 the i-th element of the small vector will be put into the ExpPos[i] position of the large vector. The position counting in the vector is assumed to start at 0 (C-like array notation).

Ipopt::ExpansionMatrixSpace::~ExpansionMatrixSpace ( ) [inline]

Destructor.

ExpansionMatrix* Ipopt::ExpansionMatrixSpace::MakeNewExpansionMatrix ( ) const [inline]

Method for creating a new matrix of this specific type.

Referenced by MakeNew().

virtual Matrix* Ipopt::ExpansionMatrixSpace::MakeNew ( ) const [inline, virtual]

Overloaded MakeNew method for the MatrixSpace base class.

Implements Ipopt::MatrixSpace.

Definition at line 148 of file IpExpansionMatrix.hpp.

References MakeNewExpansionMatrix().

const Index* Ipopt::ExpansionMatrixSpace::ExpandedPosIndices ( ) const [inline]

Accessor Method to obtain the Index array (of length NSmallVec=NCols()) that stores the mapping from the small vector to the large vector.

For each element i=0,..,NSmallVec in the small vector, ExpandedPosIndices()[i] give the corresponding index in the large vector.

const Index* Ipopt::ExpansionMatrixSpace::CompressedPosIndices ( ) const [inline]

Accessor Method to obtain the Index array (of length NLargeVec=NRows()) that stores the mapping from the large vector to the small vector.

For each element i=0,..,NLargeVec in the large vector, CompressedPosIndices()[i] gives the corresponding index in the small vector, unless CompressedPosIndices()[i] is negative.
