Inaccurate Noise Figure for Cascaded Circuits

In Version 1.0, the noise figure of a cascaded circuit was calculated using an approximate equation.
Version 1.0.1 calculates noise figure based on the noise correlation matrix.

RF Tool: Can Now Change Z0 Before Performing Analysis

In RFTool, for all components except Data File, if you changed the default characteristic impedance (Z0) before analyzing the circuit, the analysis was performed using the default value and Z0 was restored to its default.
In Version 1.0.1, the analysis is performed using the new value of Z0 and Z0 retains the new value.

RF Tool: Object Exported to Workspace Now Contains Analyzed Data

In RF Tool, if you exported an analyzed rfckt.datafile object to the workspace, the analyzed data was not exported with the object.
Version 1.0.1 fixes this problem.

Transmission Line Stub Warnings and Errors No Longer Occur

In Version 1.0, analyzing a transmission line stub object, and then making a small change to the Z0 property of the resulting rfdata.data object and analyzing the data object resulted in warnings and errors concerning matrix singularity.
Version 1.0.1 fixes this problem.
