Detailed Description

template<class MatrixType>
class Ifpack2::Hiptmair< MatrixType >

Wrapper for Hiptmair smoothers.

Template Parameters

A	specialization of Tpetra::RowMatrix.

Ifpack2::Hiptmair does smoothing on two spaces; a primary space and an auxiliary space. This situation arises when preconditioning Maxwell's equations discretized by edge elements.

For a list of all run-time parameters that this class accepts, see the documentation of setParameters().
