Detailed Description

template<class MatrixType, const bool stub = ! LapackSupportsScalar<typename MatrixType::scalar_type>::value>
class Ifpack2::Details::TriDiSolver< MatrixType, stub >

"Preconditioner" that uses LAPACK's tridi LU.

Template Parameters

MatrixType	A specialization of Tpetra::RowMatrix.
stub	Whether this is a stub implementation. The default is false. If true, then this class does nothing and its constructor throws an exception. You should always use the default value. This template parameter is an implementation detail; it prevents this class from using LAPACK for types that LAPACK does not support.

Warning

This class only works for the four types supported by LAPACK. Using any other type will result in a run-time error.
