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:
x constant 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:
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.
