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.
