Destructor. | |
Protected Member Functions | |
Overloaded methods from Matrix base class | |
virtual void | MultVectorImpl (Number alpha, const Vector &x, Number beta, Vector &y) const |
Matrix-vector multiply. | |
virtual void | TransMultVectorImpl (Number alpha, const Vector &x, Number beta, Vector &y) const |
Matrix(transpose) vector multiply. | |

Private Member Functions | |
Default Compiler Generated Methods | |
(Hidden to avoid implicit creation/calling). These methods are not implemented and we do not want the compiler to implement them for us, so we declare them private and do not define them. This ensures that they will not be implicitly created/called. | |
ExpansionMatrix () | |
Default Constructor. | |
ExpansionMatrix (const ExpansionMatrix &) | |
Copy Constructor. | |
void | operator= (const ExpansionMatrix &) |
Overloaded Equals Operator. | |
Private Attributes | |
const ExpansionMatrixSpace * | owner_space_ |
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.

Ipopt::ExpansionMatrix::ExpansionMatrix | ( | const ExpansionMatrixSpace * | owner_space | ) |
Constructor, taking the owner_space.
Ipopt::ExpansionMatrix::~ExpansionMatrix | ( | ) |
Destructor.
Ipopt::ExpansionMatrix::ExpansionMatrix | ( | ) | [private] |
Default Constructor.
Ipopt::ExpansionMatrix::ExpansionMatrix | ( | const ExpansionMatrix & | ) | [private] |
Copy Constructor.
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.

References Ipopt::ExpansionMatrixSpace::ExpandedPosIndices(), and owner_space_.
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.
