Detailed Description
implements a block diagonal PSCPrimal consisting of several PSCPrimal blocks
The partition is generated on construction and at this point the various kinds of PSCPrimal variants are also assigned to each block by a map. For some blocks the assignment may be empty so that no information is aggregated for these. Note, the partition need not match some natural partition of the original coefficient data, even if it may and will in most practical applications.
Constructor & Destructor Documentation
◆ BlockPSCPrimal()
| ConicBundle::BlockPSCPrimal::BlockPSCPrimal | ( | const CH_Matrix_Classes::Indexmatrix & | Xd, |
| const std::map< CH_Matrix_Classes::Integer, PSCPrimal *> & | pr, | ||

| ) |
in this version control over the objects pointed to in pr is passed to this. this will delete them upon its destruction
Member Function Documentation
◆ aggregate_Gram_matrix()
|
virtual |
add factor*P*P^T to this
The rows of P corresponding to each block are passed on the with a corresponding call to the PSCPrimal of this block
Implements ConicBundle::PSCPrimal.
◆ aggregate_primal_data()
|
virtual |
add factor*it to this (it must also be a BlockPSCPrimal with the same block partition)
Implements ConicBundle::PSCPrimal.
◆ assign_Gram_matrix()
|
virtual |
for each element aij in the support set aij=<P.row(i),P.row(j)>
The rows of P corresponding to each block are passed on the with a corresponding call to the PSCPrimal of this block
Implements ConicBundle::PSCPrimal.
