All systems must have the same number of inputs and outputs, but may otherwise be a mix of continuous- and discrete-time systems. Compute the standard deviations of the real and imaginary parts of the frequency response of an identified model.

For information on the ways to change properties of your plots, see Ways to Customize Plots. The nywuist arguments re and im are 3-D arrays with dimensions. The frequency points are chosen automatically based on the system poles and zeros. You have two zoom options available from the right-click menu that apply specifically to Nyquist plots:.
