◆ residual()

template<class T>

virtual void LinearOp< T >::residual	(	T &	a_lhs,
		const T &	a_phi,
		const T &	a_rhs,
		bool	a_homogeneous = `false`
	)

pure virtual

Say you are solving L(phi) = rhs. Make a_lhs = L(a_phi) - a_rhs. If a_homogeneous is true, evaluate the operator using homogeneous boundary conditions.

		const T &	a_phi,
		bool	a_homogeneous = `false`
	)

pure virtual

In the context of solving L(phi) = rhs, set a_lhs = L(a_phi). If a_homogeneous is true, evaluate the operator using homogeneous boundary conditions.

◆ create()

template<class T>

virtual void LinearOp< T >::create	(	T &	a_lhs,
		const T &	a_rhs
	)

pure virtual

Creat data holder a_lhs that mirrors a_rhs. You do not need to copy the data of a_rhs, just make a holder the same size.

◆ clear()

template<class T>

virtual void LinearOp< T >::clear ( T & a_lhs )

inlinevirtual

Opposite of create – perform any operations required before lhs goes out of scope. In general, the only time this needs to be defined in a derived class is if the create() function called new. Otherwise, the default no-op function is sufficient.

Reimplemented in MultilevelLinearOp< T >.
