◆ apply()

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

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

inlinevirtual

This method applies the operator, i.e. f = L*u (or d = J(u)*c in iterative schemes). Note, that the operator must have been initialized once before this method can be used.

Parameters

[in]	u	domain function
[out]	f	codomain function

Returns: bool success flag

Reimplemented from ug::MatrixOperator< M, X, Y >.

References ug::SchurComplementMatrixOperator< TAlgebra, M, X, Y >::m_op.

◆ apply_sub()

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

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

inlinevirtual

This method applies the operator and subracts the result from the input codomain function, i.e. f -= L*u (or d -= J(u)*c in iterative schemes). Note, that the operator must have been initialized once before this method can be used.

Parameters

[in]	u	domain function
[in,out]	f	codomain function

Returns: bool success flag

Reimplemented from ug::MatrixOperator< M, X, Y >.

◆ calculate_matrix()

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

virtual void ug::SchurComplementMatrixOperator< TAlgebra, M, X, Y >::calculate_matrix ( )

◆ init() [1/2]

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

virtual void ug::SchurComplementMatrixOperator< TAlgebra, 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

Reimplemented from ug::MatrixOperator< M, X, Y >.

◆ init() [2/2]

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

virtual void ug::SchurComplementMatrixOperator< TAlgebra, 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)
