New features and changes introduced in this version are:
An improved algorithm for the rationalfit function fits an accurate rational model to passive S-parameter data in less time than in previous versions. In addition, a new parameter specifies the number of iterations rationalfit attempts at each value for the number of poles.
Default behavior for some parameters have changed:
The number-of-poles argument npoles defaults to a minimum value of 0 in version 2.8, instead of 4, as in previous versions.
rationalfit does not display a wait bar by default in this version. A new showwaitbar parameter allows you to specify whether rationalfit displays a wait bar.
For more information on using this function, see the rationalfit reference page.
RF Toolbox version 2.8 extends the Plots and Charts methods to include:
Support for third-order intercept point and transducer power gain parameters, IIP3 and Gt.
A new method, table, for visualizing network data in the Variable Editor.
