# SingularValuePlot

 SingularValuePlot[m]gives the singular value plot of a matrix m of rational functions in one complex variable. SingularValuePlot[sys] gives the singular value plot of a TransferFunctionModel or StateSpaceModel object sys. SingularValuePlot gives the plot for frequencies from to .
• SingularValuePlot is the plot of the singular values of the sinusoidal transfer-function matrix as a function of frequency.
• The unit of frequency is radians per time unit.
• If the frequency range is not specified, an appropriate range is computed automatically.
 SamplingPeriod None the sampling period ScalingFunctions {"Log10","dB"} the scaling functions Tolerance 0 the tolerance in computing the singular values
• The frequency scale freqscale can be or , which correspond to the base-10 logarithmic scale and linear scale, respectively.
• The magnitude scale magscale can be or , which correspond to the decibel and absolute values of the magnitude, respectively.
