size_t  Rowdim,
size_t  Coldim 
)
inline

Constructor from field and dense vector of field elements.

Parameters
BBBlack box from which to extract the submatrix

colFirst column of the submatrix to extract (1.._BB_data.coldim ())
RowdimRow dimension
ColdimColumn dimension

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 LinBox vector archetype. Required by abstract base class.

Returns
reference to vector y containing output.
Parameters
xconstant reference to vector to contain input
y
OutVector& applyTranspose ( OutVector &  y,
const InVector &  x 
) const
inline

Application of BlackBox matrix transpose.

y= transpose(A)*x. Requires one vector conforming to the LinBox vector archetype. Required by abstract base class.

Returns
reference to vector y containing output.
Parameters
xconstant 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.
