What is the MATLABWebUI process?

When running Matlab, on linux at least, I see the process MATLABWebUI, I also see this when running in batch mode (i.e. launched matlab with -batch command lin switch). Usually I am using Simulink in case it is relevant. What is this process and what is it for? Is it required in batch mode?

Hi,

is it possible to run Matlab Desktop (Linux version, in my case) without MATLABWebUI?

Is it a new component introduced with R2023a? I didn't see it on R2022a.

Thanks

Giuseppe

This isn't how answers works, you need to ask a new question, not post an answer which is actually a question. It's a Q&A site not a forum.

You are right.

Thanks

Thanks to everybody. I got my answer! Now you can stop to give me trivial instructions.

@Giuseppe Di Biase what is the answer? I would like to know too (i.e. I would like to start Matlab on Linux without the MATLABWebUI process.

Hi Richard,

You can go through the following points:

• ‘MATLABWebUI’ is the process that handles the communication between the MATLAB desktop and the web-based UI (user interface) of MATLAB.
• The reason you see it on Linux when you launch MATLAB from the command line is that the MATLAB desktop environment may not be launched when running in batch mode on Linux.
• When you launch MATLAB in batch mode, it does not load the ‘MATLABDesktop’ process that handles the visual display of the MATLAB desktop UI. Instead, it relies on the ‘MATLABWebUI’ process to handle the communication between MATLAB and any web-based UI components, such as app designer or Simulink.
