Table 6-118: Properties for Study Settings
Property	Value	Default	Description
appnreigs	Integer	20	Approximate number of eigenvalues.
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 eigenvalue problems.

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.
maxnreigs	Integer	200	Maximum number of eigenvalues.
neigs	Integer	6	Desired number of eigenvalues.
neigsactive	on \| off	off	Set desired number of eigenvalues.
shift	Complex scalar	0	Shift.
shiftactive	on \| off	off	Use shift.
