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

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

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.
