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 {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.

const Field& field (   )  const [inline]
