Table 6-114: Properties for Study Settings
Property	Value	Default	Description
appnreigs	Integer	20	Approximate number of eigenfrequencies.
chkeigregion	on \| off	on	Perform consistency check.
eigli	Real scalar	0	Largest imaginary part.
eiglr	Real scalar	0	Largest real part.
eigmethod	manual \| region \| all	manual	Eigenvalue search method; the all method finds all eigenvalues for a full matrix and can only be used for small eigenfrequency problems.
eigsi	Real scalar	0	Smallest imaginary part.
eigsr	Real scalar	0	Smallest real part.
eigwhich	lm \| lr \| sr \| li \| si	lm	Eigenfrequency search method around shift.
linplistsolnum	integer array		List of solutions to use for the linearization point, when linpsolnum is set to from_list.
linpmanualsolnum	solution number		Solution number (index) to use for the linearization point, when linpsolnum is set to manual.
linpmethod	init \| sol	init	Method used for linearization point, which for sol is determined by the current solution (that is, the solution computed by the previous feature in the sequence).
linpsol	zero \| solution object	zero	Linearization point solution.
linpsolnum	all \| auto \| first \| last \| from_list \| interp \| manual \| solution number	current	Linearization point solution to use.
linpt	double		Interpolated point for the linearization point when linpsolnum is set to interp.

neigs	Integer	6	Desired number of eigenfrequencies.
neigsactive	on \| off	off	Set desired number of eigenfrequencies.
shift	Complex scalar	0	Shift.
shiftactive	on \| off	off	Use shift.
