Constructor & Destructor Documentation

Submatrix()

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

Member Function Documentation

apply()

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
y

applyTranspose()

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
y

rowdim()

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.

coldim()

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.
