Detailed Description

template<class Operator>
class Kaskade::TrivialPreconditioner< Operator >

The trivial preconditioner: this is simply the identity that does exactly nothing.

Use this as dummy preconditioner in case you don't want preconditioning for some reason (e.g., testing/debugging). For symmetric problems, consider using IdentityPreconditioner exposing the SymmetricOperator interface.

returns the category of the operator

From the Dune doxygen documentation it is unclear what this is supposed to mean. We return a dummy here.
