◆ compute() [1/2]

Teuchos::RCP< Epetra_CrsGraph > EpetraExt::BlockAdjacencyGraph::compute	(	Epetra_CrsGraph &	B,
		int	nbrr,
		std::vector< int > &	r,
		std::vector< double > &	weights,
		bool	verbose = `false`
	)

Constructs an adjacency graph representing the block connectivity of the input graph, where nbrr is the number of block rows in B and r contains the row index where each block begins.

A reference-counted pointer to an Epetra_CrsGraph that has nbrr rows is returned as well as the vector of weights. This vector is of length nbrr returns some weighting on the block adjacency graph that can be used to balance the original graph B. Right now, that weighting is just the number of rows in each block.
