Detailed Description

template<typename ValueType, typename IndexType>
class gko::experimental::solver::Direct< ValueType, IndexType >

A direct solver based on a factorization into lower and upper triangular factors (with an optional diagonal scaling). The solver is built from the Factorization returned by the provided LinOpFactory.

Template Parameters
ValueTypethe type used to store values of the system matrix
IndexTypethe type used to store sparsity pattern indices of the system matrix

Constructor & Destructor Documentation

◆ Direct() [1/2]

template<typename ValueType , typename IndexType >
gko::experimental::solver::Direct< ValueType, IndexType >::Direct ( const Direct< ValueType, IndexType > &  )

Creates a copy of the solver.

◆ Direct() [2/2]

template<typename ValueType , typename IndexType >
gko::experimental::solver::Direct< ValueType, IndexType >::Direct ( Direct< ValueType, IndexType > &&  )

Moves from the given solver, leaving it empty.

Member Function Documentation

◆ conj_transpose()

template<typename ValueType , typename IndexType >
std::unique_ptr< LinOp > gko::experimental::solver::Direct< 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.

◆ parse()

template<typename ValueType , typename IndexType >
static parameters_type gko::experimental::solver::Direct< 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
configthe property tree for setting
contextthe registry
td_for_childthe type descriptor for children configs. The default uses the value/index type of this class.
Returns
parameters

◆ transpose()

template<typename ValueType , typename IndexType >
std::unique_ptr< LinOp > gko::experimental::solver::Direct< 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.
