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. | |
ExpandedMultiVectorMatrix () | |
Default Constructor. | |
ExpandedMultiVectorMatrix (const ExpandedMultiVectorMatrix &) | |
Copy Constructor. | |
void | operator= (const ExpandedMultiVectorMatrix &) |
Overloaded Equals Operator. | |

Class for Matrices with few rows that consists of Vectors, together with a premultiplied Expansion matrix.
So, the matrix is V^T*P^T. If P is NULL, it is assumed to be the identity matrix. If a row vector of V is NULL, it is assumed to be all zero. This is used to construct the KKT system with low-rank Hessian approximation.
