Detailed Description

Epetra_OskiPermutation: A class for storing the permutation performed on a Epetra_OskiMatrix.

The Epetra_OskiPermutation is one of the possible transformations that OSKI can perform on a matrix. The permutation is stored with the matrix in OSKI. Using this class a Epetra_OskiPermutation can be applied to an Epetra_OskiMultiVector.

Source

)

Copy Constructor.

Epetra_OskiPermutation::Epetra_OskiPermutation	(	bool	RowPerm,
		const Epetra_OskiMatrix &	Source
	)

Constructor creates an Epetra_OskiPermutation from an Epetra_OskiMatrix.

Acquires the permutation from the passed in matrix and stores it within the object. If RowPerm is true this is a row permutation and if RowPerm is false this is a column permutation.

Member Function Documentation

void Epetra_OskiPermutation::ReplacePermutation

(

const oski_perm_t &

InPerm

)

Stores a permutation in the data structure.

int Epetra_OskiPermutation::PermuteVector	(	const bool	TransA,
		Epetra_OskiMultiVector &	Vector
	)		const

Permutes Vector according to the Permutation. If a transpose is desired it performs that operation.

The Vector passed into this function is a view. It is the underlying object that is permuted by the function.

Parameters

TransA	(In) If TransA = TRUE then use the transpose of the permutation and apply it to Vector.
Vector	(In/Out) The vector that is permuted by Permutation^Trans.

Returns

When successful returns 0. On error Vector is not permuted and a error code is returned.
