inlineinherited

Parameters

[in]	unnamed
[in]	unnamed

References ILinearIterator< X, Y >::apply_update_defect().

clone()

SmartPtr<ILinearIterator> clone ( )

inlineinherited

returns a clone of the object which can be modified independently

Returns

SmartPointer to a copy of this object

References ILinearIterator< X, Y >::clone().

config_string()

std::string config_string ( ) const

inlineinherited

string to display configuration of the linear iterator

Returns

strConfiguration

References ILinearIterator< X, Y >::config_string().

enable_consistent_interfaces()

void enable_consistent_interfaces ( bool  enable )

inline

Make Matrix consistent for connections in interfaces.

Parameters

inlineinherited

References ILinearIterator< X, Y >::name().

set_beta()

void set_beta ( double  beta )

inline

Parameters

[in]

beta

References ILU< TAlgebra >::set_beta().

set_damp()

void set_damp ( double  damp )

set the damping to a number

Parameters

[in]

damp

References ILinearIterator< X, Y >::set_damp().

set_disable_preprocessing()

void set_disable_preprocessing ( bool  disable )

inline

set whether preprocessing (notably, LU factorization) is to be disabled - usable when the operator has not changed; use with care

Parameters

disable

References ILU< TAlgebra >::set_disable_preprocessing().

set_inversion_eps()

void set_inversion_eps ( double  eps )

inline

Parameters

[in]

set_sort_eps()

void set_sort_eps ( double  eps )

inline

Parameters

[in]
