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 Blackbox *    A_ptr )  [inline]

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

~Transpose (  void    )  [inline]

Destructor.

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 \Ref{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 \Ref{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 coldim (  void    )  const [inline]

Retreive column dimensions of BlackBox matrix. Required by abstract base class. Returns: integer number of columns of black box matrix.

const Field& field (    )  const [inline]

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.
