Detailed Description

template<class Scalar>
class TSQR::Test::FullTsqrVerifier< Scalar >

Test (correctness and) accuracy of Tsqr for one Scalar type.

Author:
Mark Hoemmen

This class is meant to be used only by FullTsqrVerifierCaller. It performs one accuracy test of Tsqr for the given Scalar type (that is, the type of the matrix entries). An accuracy test is also a correctness test. This test computes accuracy bounds for both orthogonality and forward errors, and if those bounds are exceeded and the failIfInaccurate option is enabled, the test will throw a TsqrInaccurate exception.

The test takes a Teuchos::ParameterList input. For a ParameterList with all parameters, their default values, and documentation, see the relevant class method in FullTsqrVerifierCaller.

This class currently only tests the version of Tsqr that is the composition of NodeTsqrType=SequentialTsqr and DistTsqrType=DistTsqr. This should suffice to test correctness, as long as the other NodeTsqrType possibilities (such as TbbTsqr) are tested separately.
