Member Function Documentation

AbstractLinAlgPack::DirectSparseSolverMA28::STANDARD_MEMBER_COMPOSITION_MEMBERS	(	value_type	,
		u
	)

Pivot tolerance versus sparsity.

AbstractLinAlgPack::DirectSparseSolverMA28::STANDARD_MEMBER_COMPOSITION_MEMBERS	(	bool	,
		grow
	)

If true, than an estimate of growth of the factors is computed.

AbstractLinAlgPack::DirectSparseSolverMA28::STANDARD_MEMBER_COMPOSITION_MEMBERS	(	value_type	,
		tol
	)

Drop tolerance for an incomplete factorization.

AbstractLinAlgPack::DirectSparseSolverMA28::STANDARD_MEMBER_COMPOSITION_MEMBERS	(	index_type	,
		nsrch
	)

Number of columns to search to reduce fill-in.

AbstractLinAlgPack::DirectSparseSolverMA28::STANDARD_MEMBER_COMPOSITION_MEMBERS	(	bool	,
		lbig
	)

If true, then the largest entry encountered is returned.

AbstractLinAlgPack::DirectSparseSolverMA28::STANDARD_MEMBER_COMPOSITION_MEMBERS	(	bool	,
		print_ma28_outputs
	)

If true, then outputs from ma28 are printed to output stream.

AbstractLinAlgPack::DirectSparseSolverMA28::STANDARD_MEMBER_COMPOSITION_MEMBERS	(	std::string	,
		output_file_name
	)

If output_file != "", then output from MA28 is sent to this file.
