Destructor


Member Function Documentation

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

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:
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 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.
