int EpetraExt_PointToBlockDiagPermute::SetParameters ( Teuchos::ParameterList & List )

virtual

Sets the parameter list.

Definition at line 137 of file EpetraExt_PointToBlockDiagPermute.cpp.

virtual int EpetraExt_PointToBlockDiagPermute::SetUseTranspose ( bool )

inlinevirtual

Set whether to use the transpose.

Returns: 0 if this class can change its transpose state, else nonzero.

This class does NOT know how to apply its transpose, so this method always returns an error code.

Implements Epetra_Operator.

int EpetraExt_PointToBlockDiagPermute::Compute ( )

virtual

Extracts the block-diagonal, builds maps, etc.

int EpetraExt_PointToBlockDiagPermute::Apply	(	const Epetra_MultiVector &	X,
		Epetra_MultiVector &	Y
	)		const

virtual

Returns the result of a Epetra_Operator applied to a Epetra_MultiVector X in Y.

Parameters

In	X - A Epetra_MultiVector of dimension NumVectors to multiply with matrix.
Out	Y -A Epetra_MultiVector of dimension NumVectors containing result.

Returns: Integer error code, set to 0 if successful.

Implements Epetra_Operator.

Definition at line 162 of file EpetraExt_PointToBlockDiagPermute.cpp.

int EpetraExt_PointToBlockDiagPermute::ApplyInverse	(	const Epetra_MultiVector &	X,

	)		const

virtual

Returns the result of a Epetra_Operator inverse applied to an Epetra_MultiVector X in Y.

Parameters

In	X - A Epetra_MultiVector of dimension NumVectors to solve for.
Out	Y -A Epetra_MultiVector of dimension NumVectors containing result.

Returns: Integer error code, set to 0 if successful.

Warning: In order to work with AztecOO, any implementation of this method must support the case where X and Y are the same object.
