Member Function Documentation

apply()

template<class Blackbox>

template<class Vector1, class Vector2>

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

x	constant reference to vector to contain input
y

applyTranspose()

template<class Blackbox>

template<class Vector1, class Vector2>

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
y

rowdim()

template<class Blackbox>

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()

template<class Blackbox>

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.

field()

template<class Blackbox>

const Field & field ( ) const

getData() [1/2]

template<class Blackbox>

const Blackbox & getData ( ) const

inline

getData() [2/2]

template<class Blackbox>

Blackbox & getData ( )

inline
