Detailed Description

The SystemMatrixOrdering class provides an interface for defining classes that allows to reorder the system matrix.

If the system is partitioned, each process can reorder only it's local part of the matix.

◆ getColPermutationRank()

virtual long bitpit::SystemMatrixOrdering::getColPermutationRank ( long col ) const

pure virtual

Get the rank of the specified local column.

The permutation rank defines the position, in the final assembled matrix, of the specified local column (i.e., the position of the specified local column after applying the reordering).

Parameters

col	is the local column

Returns: The rank of the specified local column.

Implemented in bitpit::NaturalSystemMatrixOrdering, and bitpit::ProxySystemMatrixOrdering< RowRankStorage, ColRankStorage >.

◆ getRowPermutationRank()

virtual long bitpit::SystemMatrixOrdering::getRowPermutationRank ( long row ) const

pure virtual

Get the rank of the specified local row.

The permutation rank defines the position, in the final assembled matrix, of the specified local row (i.e., the position of the specified local row after applying the reordering).
