Constructor & Destructor Documentation

viennacl::linalg::ilut_tag::ilut_tag ( unsigned int  entries_per_row = 20,
double  drop_tolerance = 1e-4,
bool  with_level_scheduling = false 

The constructor.

entries_per_rowNumber of nonzero entries per row in L and U. Note that L and U are stored in a single matrix, thus there are 2*entries_per_row in total.
drop_toleranceThe drop tolerance for ILUT
with_level_schedulingFlag for enabling level scheduling on GPUs.
