◆ AdditionalData()

template<typename Number >
CUDAWrappers::PreconditionIC< Number >::AdditionalData::AdditionalData ( bool  use_level_analysis = true)

Constructor. cuSPARSE allows to compute and use level information. According to the documentation this might improve performance. It is suggested to try both options.
