Hi Yair,

This has been a great help.
With the removal of com.mathworks sometime in the future (as announced in R2020b), is there an alternative?
For me, just getting a preference value programmatically would be enough. I am not interested in setting them.

Thanks,
Robin

Hi Yair,
I am trying to change keybindings to certain keys for many systems is there any way that we can change these settings.
i can change in window dialogue like Home>Environment>Preferences>keyboard>Shortcuts > then i select shortcut and change ….can we do it through code like above ? I tried many things but didn’t able get it to work

In reply to Parvaneh. @Parvaneh - you will need to check the web for a utility that has a command-line interface that does what you want, and then you can call that utility from Matlab using the system command.

Hi Yair,

I was looking for a way to change the setting of the system using matlab when I saw this post.
I wonder if you can help me with it.
I’m connecting two monitors and I want to run a program from one monitor and make it run on the other one.
In the process I need to change setting from ‘screen resolution’ in the control panel.
Could this be done with matlab?

I would appreciate any help.

Thanks,
Parvaneh

Hi Yair, Thanks for this article! I took inspiration from it to create a package to import and export color schemes in MATLAB. This definitely would not have been possible without undocumentedmatlab! It is available on GitHub and FileExchange. All the best, Scott

To change Parallel Pool settings:

 
ps = parallel.Settings;
ps.Pool
ans = 
  PoolSettings with properties:
                            AutoCreate: 0
                RestartOnClusterChange: 1
    RestartOnPreferredNumWorkersChange: 1
                           IdleTimeout: 30
                   PreferredNumWorkers: 12

I just learned once more that it’s extremely helpful to programmatically check for the correct “MatfileSaveFormat” property to avoid being unable to save (or later: load) your results. Thanks for your helpful post!
