Parameters
Matconstant reference to compose black box matrix

Member Function Documentation

Vector1& apply ( Vector1 &  y,
const Vector2 &  x 
) const
inline

Application of BlackBox matrix.

y = P(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
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
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.
