Constructor & Destructor Documentation

EpetraExt::BlockVector::BlockVector	(	const Epetra_BlockMap &	BaseMap,
		const Epetra_BlockMap &	GlobalMap
	)

BlockVector constuctor with one block row per processor.

Creates a BlockVector object and allocates storage.

Parameters:

	In	BaseMap - Map determining local structure, can be distrib. over subset of proc.'s
	In	GlobalMap - Full map describing the overall global structure, generally generated by the construction of a BlockCrsMatrix object
	In	NumBlocks - Number of local blocks

Definition at line 38 of file EpetraExt_BlockVector.cpp.

EpetraExt::BlockVector::BlockVector	(	Epetra_DataAccess	CV,
		const Epetra_BlockMap &	BaseMap,
		const Epetra_Vector &	BlockVec
	)

Creates a BlockVector object from an existing Epetra_Vector.

Parameters:

	In	Epetra_DataAccess - Enumerated type set to Copy or View.
	In	BaseMap - Map determining local structure, can be distrib. over subset of proc.'s
	In	BlockVec - Source Epetra vector whose map must be the full map for the block vector
