Detailed Description

Class for expansion/projection matrices.

These matrices allow to lift a vector to a vector with larger dimension, keeping some elements of the larger vector zero. This operation is achieved by the MultVector operation. The transpose operation then filters some elements from a large vector into a smaller vector.

Member Function Documentation

const Index * Ipopt::ExpansionMatrix::ExpandedPosIndices ( ) const
inline

Return the vector of indices marking the expanded position.

The result is 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.

Definition at line 200 of file IpExpansionMatrix.hpp.

const Index * Ipopt::ExpansionMatrix::CompressedPosIndices ( ) const
inline

Return the vector of indices marking the compressed position.

The result is 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.
