Constructor & Destructor Documentation

ilut_tag	(	unsigned int	entries_per_row = 20,
		double	drop_tolerance = 1e-4
	)			[inline]

The constructor.

Parameters:

	entries_per_row	Number 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_tolerance	The drop tolerance for ILUT
