Member Function Documentation

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

Application of BlackBox matrix.

y= (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

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

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.
