Is it possible to retrieve the command window output from a worker when using parfeval? Specifically I'd like to catch listener errors that are typically printed out as warnings (normal messages) in the command window.

Thanks for the links. I'm curious as to how pmode works with parfeval. I'll have to give it a try when I get a chance.
The second question seems to be unanswered. At some point I was getting errors on quitting Matlab and wanted to know what was being printed to the command window. Thinking myself clever I setup a diary. Unfortunately, as the poster is pointing out, if you don't close the diary you don't get the output. Thus I've never found a good way of properly capturing the command window output (whether in the client or in a worker).
Although now that I think about it is possible to grab the client's command window text (I think) and thus if I ran the same code on the worker that might work as well ...

Presumably you could use this when run in the worker ... https://www.mathworks.com/matlabcentral/fileexchange/31438-command-window-text
