# SingularValuePlot

SingularValuePlot[lsys]
generates a plot of the singular values of the transfer function for the system lsys.

SingularValuePlot[lsys,{ωmin,ωmax}]
plots for the frequency range ωmin to ωmax.

SingularValuePlot[expr,{ω,ωmin,ωmax}]
plots expr using the variable ω.

## Details and OptionsDetails and Options

• The system lsys can be TransferFunctionModel or StateSpaceModel, including descriptor and delay systems.
• For a system lsys with the corresponding transfer function , the following expressions are plotted:
•  continuous-time system discrete-time system with sample time
• SingularValuePlot treats the variable ω as local, effectively using Block.
• SingularValuePlot has the same options as Plot, with the following additions and changes:
•  SamplingPeriod None the sampling period ScalingFunctions {"Log10","dB"} the scaling functions Tolerance 0 the tolerance in computing the singular values
• The scaling functions can be specified as ScalingFunctions->{freqscale,magscale}.
• The frequency scale freqscale can be "Log10" or "Linear", which correspond to the base-10 logarithmic scale and linear scale, respectively.
• The magnitude scale magscale can be "dB" or "Absolute", which correspond to the decibel and absolute values of the magnitude, respectively.
