Constructor & Destructor Documentation

Submatrix	(	const Blackbox *	BB,
		size_t	row,
		size_t	col,
		size_t	Rowdim,
		size_t	Coldim
	)		[inline]

Constructor from field and dense vector of field elements.

Parameters:

BB	Black box from which to extract the submatrix
row	First row of the submatrix to extract (1.._BB->rowdim ())
col	First column of the submatrix to extract (1.._BB->coldim ())
Rowdim	Row dimension
Coldim	Column dimension

Reimplemented in Submatrix< Blackbox, VectorCategories::DenseZeroOneVectorTag >.

Member Function Documentation

OutVector& apply	(	OutVector &	y,
		const InVector &	x
	)		const [inline]

Application of BlackBox matrix.

y= A*x. Requires one vector conforming to the LinBox vector archetype. Required by abstract base class.

Returns:

reference to vector y containing output.

Parameters:

x	constant reference to vector to contain input
y

OutVector& applyTranspose	(	OutVector &	y,
		const InVector &	x
	)		const [inline]

Application of BlackBox matrix transpose.

y= transpose(A)*x. Requires one vector conforming to the LinBox vector archetype. Required by abstract base class.

Returns:

reference to vector y containing output.

Parameters:

x	constant reference to vector to contain input
y

size_t rowdim

(

void

)

const [inline]

Retreive _row dimensions of BlackBox matrix.

This may be needed for applying preconditioners. Required by abstract base class.

Returns:

integer number of _rows of black box matrix.

size_t coldim

(

void

)

const [inline]

Retreive _column dimensions of BlackBox matrix.

Required by abstract base class.

Returns:

integer number of _columns of black box matrix.
