Detailed Description

template<class Scalar, class MV, class OP>
class Anasazi::TsqrMatOrthoManager< Scalar, MV, OP >

MatOrthoManager subclass using TSQR or SVQB.

When the inner product matrix has not been set, this class uses TSQR + Block Gram-Schmidt (via TsqrOrthoManagerImpl). If the inner product matrix has been set, then this class uses the SVQB algorithm (Stathopoulos and Wu 2002: CholeskyQR + SVD) for orthogonalization.

TSQR uses multivector scratch space. However, scratch space initialization is "lazy," so scratch space will not be allocated if TSQR is not used.

Constructor & Destructor Documentation

template<class Scalar , class MV , class OP >
Anasazi::TsqrMatOrthoManager< Scalar, MV, OP >::TsqrMatOrthoManager ( const Teuchos::RCP< Teuchos::ParameterList > &  params,
const std::string &  label = "Belos",
Teuchos::RCP< const OP >  Op = Teuchos::null 
)
inline

Constructor (that sets user-specified parameters).

Parameters
params[in/out] Configuration parameters, both for this orthogonalization manager, and for TSQR itself (as the "TSQR implementation" sublist). This can be null, in which case default parameters will be set for now; you can always call setParameterList() later to change these.
label[in] Label for timers. This only matters if the compile-time option for enabling timers is set.
Op[in] Inner product with respect to which to orthogonalize vectors. If Teuchos::null, use the Euclidean inner product.

Call getValidParameters() for default parameters and their documentation, including TSQR implementation parameters. Call getFastParameters() to get documented parameters for faster computation, possibly at the expense of accuracy and robustness.

Parameters
Op[in] Inner product with respect to which to orthogonalize vectors. If Teuchos::null, use the Euclidean inner product.

Get "fast" parameters for TsqrMatOrthoManager.

Get a (pointer to a) list of parameters for configuring a TsqrMatOrthoManager instance for maximum speed, at the cost of accuracy (no block reorthogonalization) and robustness to rank deficiency (no randomization of the null space basis).
