This figure shows the nyquist plot with a data marker.
You will then see the widget on your iGoogle account. Compute the standard deviations of the real and imaginary parts of the frequency response of an identified model. Tight —Clips unbounded branches of the Nyquist plot, but still includes the critical point -1, 0 On -1,0 — Zooms around the critical point -1,0. When invoked without left-hand arguments, nyquist produces a Nyquist plot on the screen. Select the China site in Chinese or English for best site performance.

Nyquist plots are used to analyze system properties including gain margin, phase margin, and stability. For information on the ways to change properties of your plots, see Ways to Customize Plots. The frequency points are chosen automatically based on the system poles and zeros.
