class LinBox::Transpose< Blackbox >

transpose matrix without copying.

Parameters:
VectorLinBox} dense or sparse vector of field elements

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_ptrpointer to black box matrix.
Transpose ( const Transpose< Blackbox > &  M) [inline]

Copy constructor. Creates new black box objects in dynamic memory.

Parameters:
Mconstant reference to compose black box matrix

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:
xconstant 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:
xconstant 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.
