Detailed Description

template<typename ValueType = default_precision, typename IndexType = int32>
class gko::solver::LowerTrs< ValueType, IndexType >

LowerTrs is the triangular solver which solves the system L x = b, when L is a lower triangular matrix. It works best when passing in a matrix in CSR format. If the matrix is not in CSR, then the generate step converts it into a CSR matrix. The generation fails if the matrix is not convertible to CSR.

Note: As the constructor uses the copy and convert functionality, it is not possible to create a empty solver or a solver with a matrix in any other format other than CSR, if none of the executor modules are being compiled with.

Template Parameters

ValueType	precision of matrix elements
IndexType	precision of matrix indices

Constructor & Destructor Documentation

◆ LowerTrs() [1/2]

template<typename ValueType = default_precision, typename IndexType = int32>

gko::solver::LowerTrs< ValueType, IndexType >::LowerTrs ( const LowerTrs< ValueType, IndexType > & )

Copy-assigns a triangular solver. Preserves the executor, shallow-copies the system matrix. If the executors mismatch, clones system matrix onto this executor. Solver analysis information will be regenerated.

◆ LowerTrs() [2/2]

template<typename ValueType = default_precision, typename IndexType = int32>

gko::solver::LowerTrs< ValueType, IndexType >::LowerTrs ( LowerTrs< ValueType, IndexType > && )

Move-assigns a triangular solver. Preserves the executor, moves the system matrix. If the executors mismatch, clones system matrix onto this executor and regenerates solver analysis information. Moved-from object is empty (0x0 and nullptr system matrix)

Member Function Documentation

◆ conj_transpose()

template<typename ValueType = default_precision, typename IndexType = int32>

std::unique_ptr< LinOp > gko::solver::LowerTrs< ValueType, IndexType >::conj_transpose ( ) const

overridevirtual

Returns a LinOp representing the conjugate transpose of the Transposable object.

Returns: a pointer to the new conjugate transposed object

Implements gko::Transposable.

◆ generate()

template<typename ValueType = default_precision, typename IndexType = int32>

void gko::solver::LowerTrs< ValueType, IndexType >::generate ( )

protected

Generates the analysis structure from the system matrix and the right hand side needed for the level solver.

◆ operator=() [1/2]

template<typename ValueType = default_precision, typename IndexType = int32>

LowerTrs & gko::solver::LowerTrs< ValueType, IndexType >::operator= ( const LowerTrs< ValueType, IndexType > & )

Copy-constructs a triangular solver. Preserves the executor, shallow-copies the system matrix. Solver analysis information will be regenerated.

◆ operator=() [2/2]

template<typename ValueType = default_precision, typename IndexType = int32>

LowerTrs & gko::solver::LowerTrs< ValueType, IndexType >::operator= ( LowerTrs< ValueType, IndexType > && )

Move-constructs a triangular solver. Preserves the executor, moves the system matrix and solver analysis information. Moved-from object is empty (0x0 and nullptr system matrix)

◆ parse()

template<typename ValueType = default_precision, typename IndexType = int32>

static parameters_type gko::solver::LowerTrs< ValueType, IndexType >::parse	(	const config::pnode &	config,
		const config::registry &	context,
		const config::type_descriptor &	td_for_child = `config::make_type_descriptor< ValueType, IndexType >()`
	)

static

Create the parameters from the property_tree. Because this is directly tied to the specific type, the value/index type settings within config are ignored and type_descriptor is only used for children configs.

Parameters

config	the property tree for setting
context	the registry
td_for_child	the type descriptor for children configs. The default uses the value/index type of this class.

Returns: parameters

◆ transpose()

template<typename ValueType = default_precision, typename IndexType = int32>

std::unique_ptr< LinOp > gko::solver::LowerTrs< ValueType, IndexType >::transpose ( ) const

overridevirtual

Returns a LinOp representing the transpose of the Transposable object.

Returns: a pointer to the new transposed object

Implements gko::Transposable.
