UDPPort warning when using MovingSource.read

[saraylet]

When warnings are turned on, I receive the following error when using MovingSource.read and also when just loading the .mat file manually using MATLAB.

Warning: Cannot load an object of class 'UDPPort':
Its class cannot be found. 

For example, this happens on a Linux/Ubuntu machine when loading LAST.01.01.01_20240108.193342.366_clear_043+18_101_001_001_sci_merged_Asteroids_1.mat

This may be related to antiquated/unsupported types in MATLAB.

us this happens with any file you are trying to load? or only with this specific file? Is this happening with your new computer? Is it happening on other computers? AstroPack doesn't use UDP directly, so its likely an internal matlab warning.

I receive this warning for every successful MovingSources.read performed on my new Linux machine.

[EranOfek]

is it happens also when you try to use the "load" function directly? It likely related to your new linux machine, did you consult with Amir/Arie?

class udpport has been introduced in matlab 2020b to replace the deprecated udp, analogously to serialport aiming to replace serial. My educated guess is that this file LAST.01.01.01_20240108.193342.366_clear_043+18_101_001_001_sci_merged_Asteroids_1.mat embowels one of such objects somehow (I don't want to know how and where), has been saved by a recent Matlab and is being loaded in an older version.

Users of udp might be your system loggers, what do I know. Many AstroPack classes have a Logging property for purposes I prefer not to know, maybe that is the injector

Thanks Enrico, this may be the answer. I suspect this is related to the syslog capabilities added by Arie. Arie - any idea?
