Constructor & Destructor Documentation

Transpose

(

const Blackbox &

A

)

[inline]

Constructor from a black box. This constructor creates a matrix that the transpose of a black box matrix A

Parameters:

A_ptr

pointer to black box matrix.

Transpose

(

const Transpose< Blackbox > &

M

)

[inline]

Copy constructor. Creates new black box objects in dynamic memory.

Parameters:

M

constant reference to compose black box matrix

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

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

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.
