Member Function Documentation

OutVector& apply (  OutVector &    y, const InVector &    x )  const [inline]

Application of BlackBox matrix. y= A*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

OutVector& applyTranspose (  OutVector &    y, const InVector &    x )  const [inline]

Application of BlackBox matrix transpose. y= transpose(A)*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.

Submatrix (  const Blackbox *    BB, size_t    row, size_t    col, size_t    rowdim, size_t    coldim )  [inline]

Constructor from field and dense vector of field elements. Parameters: BB  Black box from which to extract the submatrix row  First row of the submatrix to extract (1.._BB->rowdim ()) col  First column of the submatrix to extract (1.._BB->coldim ()) rowdim  Row dimension coldim  Column dimension
