Constructor & Destructor Documentation

AdditionalData() [1/2]

template<typename VectorType = Vector<double>>

SolverCG< VectorType >::AdditionalData::AdditionalData ( const bool  log_coefficients, const bool  compute_condition_number = false, const bool  compute_all_condition_numbers = false, const bool  compute_eigenvalues = false  )

explicit

Constructor. Initialize data fields. Confer the description of those.

Deprecated:

Instead use: connect_coefficients_slot, connect_condition_number_slot, and connect_eigenvalues_slot.

AdditionalData() [2/2]

template<typename VectorType = Vector<double>>

SolverCG< VectorType >::AdditionalData::AdditionalData

(

)

Constructor. Initializes all data fields to false.
