BlockVector constuctor with one block row per processor.
Teuchos::RCP< const Epetra_Vector > GetBlock(long long BlockRow) const
Return Epetra_Vector for given block row.
int LoadBlockValues(const Epetra_Vector &BaseVec, long long BlockRow)
Load a single block into a Block Vector: block row is global, not a stencil value.
double * Values() const
