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. | |
LowRankUpdateSymMatrix () | |
Default Constructor. | |
LowRankUpdateSymMatrix (const LowRankUpdateSymMatrix &) | |
Copy Constructor. | |
void | operator= (const LowRankUpdateSymMatrix &) |
Overloaded Equals Operator. | |
Private Attributes | |
SmartPtr< const LowRankUpdateSymMatrixSpace > | owner_space_ |
corresponding matrix space | |
SmartPtr< const Vector > | D_ |
Vector storing the diagonal matrix D. | |
SmartPtr< const MultiVectorMatrix > | V_ |
Vector storing the positive low-rank update. | |
SmartPtr< const MultiVectorMatrix > | U_ |
Vector storing the negative low-rank update. |
The matrix M is represented as M = P_LR(D + V V^T - U U^T)P_LR^T (if reduced_diag is true), or M = D + P_LR(V V^T - U U^T)P_LR^T (if reduced_diag is false). D is a diagonal matrix, and V and U are MultiVectorMatrices, and P_LR is an ExpansionMatrix. The vectors in the low-rank update (before expansion) live in the LowRankVectorSpace. If P_LR is NULL, P_LR is assumed to be the identity matrix. If V or U is NULL, it is assume to be a matrix of zero columns.
