Build a new widget. Description nyquist creates a Nyquist plot of the frequency response of a dynamic system model.
Tips You can change the properties of your plot, for example the units. Here re ddiagramme im are the real and imaginary parts of the frequency response, and sdre and sdim are their standard deviations, respectively. This figure shows the M circles for transfer function H. Tight —Clips unbounded branches nyqkist the Nyquist plot, but still includes the critical dlagramme -1, 0.
To add the widget to iGoogle, click here. 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. To add the widget to Blogger, click here and follow the easy directions provided by Blogger.
To add a widget to a MediaWiki site, the wiki must have the Widgets Extension installed, as well as the code for the Wolfram Alpha widget.
