Inputs

Type	Name	Default	Description
StateSpace	ss		State space system
Integer	nPoints	200	Number of points
Boolean[:,:]	autoRange	fill(true, size(ss.C, 1), size(ss.B, 2))	True, if abszissa range is automatically determined
Modelica.Units.SI.Frequency[:,:]	f_min	fill(0.1, size(ss.C, 1), size(ss.B, 2))	Minimum frequency value, if autoRange = false
Modelica.Units.SI.Frequency[:,:]	f_max	fill(10, size(ss.C, 1), size(ss.B, 2))	Maximum frequency value, if autoRange = false
Boolean	magnitude	true	= true, to plot magnitude
Boolean	phase	true	= true, to plot phase
Real	tol	1e-10	Tolerance of reduction procedure, default tol = 1e-10
Plot.Records.Diagram	defaultDiagram (from PartialPlotFunction)		Default diagram layout
Plot.Records.Device	device (from PartialPlotFunction)	Modelica_LinearSystems2.Utilities.Plot.Records.Device()	Properties of device where figure is shown
Boolean	Hz	true	= true, to plot abszissa in [Hz], otherwise in [rad/s] (= 2piHz)
Boolean	dB	false	= true, to plot magnitude in [-], otherwise in [dB] (=20*log10(value))
Boolean	onFile	false	= true, if frequency response is stored on file as matrix [f,a,phi]
String	fileName	"frequencyResponse.mat"	If onFile=true, file on which the frequency response will be stored
String	matrixName	if Hz and not dB then "fHz_a_phiDeg" elseif Hz and dB then "fHz_adB_phiDeg" elseif not Hz and dB then "f_adB_phiDeg" else "f_a_phiDeg"	If onFile=true, prefix name of matrix on file
