% convert to RSS in dBm and resultant signal phase offset
RSS = 10*log10(abs(rayPower)/.001); % dBm

save("data.mat","data")
The above code works as expected however, running:
load("data.mat")
Will result in the following warnings being spammed in the console:
> In <FUNCTION> (line 25)
Warning: Unable to load C++ object. Saving (serializing) C++ objects into a MAT-file is not supported.

Warning: Cannot load an object of class ‘proplistener’:

I thought foriclby closing the siteviewer would work (or at least get rid of the last error), but it has not seemed to have an effect. What command should I run to fix this behavior?
