apply()

template<typename M , typename X , typename Y = X>

virtual void ug::MatrixOperator< M, X, Y >::apply ( Y &  f, const X &  u  )

inlinevirtual

Reimplemented in ug::AssembledLinearOperator< TAlgebra >.

apply_sub()

template<typename M , typename X , typename Y = X>

virtual void ug::MatrixOperator< M, X, Y >::apply_sub ( Y &  f, const X &  u  )

get_matrix()

template<typename M , typename X , typename Y = X>

virtual M& ug::MatrixOperator< M, X, Y >::get_matrix ( )

inlinevirtual

Reimplemented in ug::SchurComplementMatrixOperator< TAlgebra, M, X, Y >.

Referenced by ug::MatAdd(), ug::MatIdentity(), ug::MatScale(), ug::MatTranspose(), and ug::SaveMatrixToMTX().

init() [1/2]

template<typename M , typename X , typename Y = X>

virtual void ug::MatrixOperator< M, X, Y >::init ( )

inlinevirtual

init operator

This method initializes the operator. Once initialized the 'apply'-method can be called. If the operator is a linearization this function returns false.

Returns

bool success flag

Implements ug::ILinearOperator< X, X >.

Reimplemented in ug::AssembledLinearOperator< TAlgebra >, and ug::SchurComplementMatrixOperator< TAlgebra, M, X, Y >.

init() [2/2]

template<typename M , typename X , typename Y = X>

virtual void ug::MatrixOperator< M, X, Y >::init ( const X &  u )

inlinevirtual

init operator depending on a function u

This method initializes the operator. Once initialized the 'apply'-method can be called. The function u is passed here, since the linear operator may be the linearization of some non-linear operator. Thus, the operator depends on the linearization point. If the operator is not a linearization, this method can be implemented by simply calling init() and forgetting about the linearization point.

Parameters

[in]

u

function (linearization point)

Returns

bool success flag

Implements ug::ILinearOperator< X, X >.

Reimplemented in ug::SchurComplementMatrixOperator< TAlgebra, M, X, Y >, and ug::AssembledLinearOperator< TAlgebra >.
