	)		const [inline]

Application of BlackBox matrix.

y = P(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

Vector1& applyTranspose	(	Vector1 &	y,
		const Vector2 &	x
	)		const [inline]

Application of BlackBox matrix transpose.

y= transpose(A*B)*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
