sigma
Singular values of frequency response. If no output arguments are given, the singular value plot is printed on the screen.
Inputs
LTI system. Multiple inputs and/or outputs (MIMO systems) make practical sense.
Optional vector of frequency values. If w is not specified,
it is calculated by the zeros and poles of the system.
Alternatively, the cell {wmin, wmax} specifies a frequency range,
where wmin and wmax denote minimum and maximum frequencies
in rad/s.
Line style and color, e.g. ’r’ for a solid red line or ’-.k’ for a dash-dotted
black line. See help plot for details.
Outputs
Array of singular values. For a system with m inputs and p outputs, the array sv
has min (m, p) rows and as many columns as frequency points length (w).
The singular values at the frequency w(k) are given by sv(:,k).
Vector of frequency values used.
