How can I pass Z-parameters as a parameter input to the plot function of the rfckt.cascade object within the RF Toolbox 2.3 (R2008a)?

I am using the "rfckt.cascade" object to create a tee network using the RF Toolbox 2.3.

I am able to analyze and plot the S-parameters of this object successfully, but I need to view the plot of the Z-parameters of this object. However, the PLOT function of the "rfckt.cascade" object does not accept Z-parameters z11, z21, etc. as valid arguments.

The ability to do pass Z-parameters as input arguments to the "plot" function of the "rfckt.cascade" object is not available in the RF Toolbox.

As a workaround, use the S2Z function to convert S-parameters from the "AnalyzedResult.S_Parameter" field of the "rfckt.cascade" object into the equivalent Z parameters. Then, replace the "AnalyzedResult.S_Parameter" with the output of the S2Z function and plot the results of the "rfckt" object.
