MATLAB: Busy forever in Matlab R2019a

busy foreverMATLAB

Running R2019a under Windows 10, I suddenly find that various commands cause Matlab to enter the 'busy' state forever. The only recourse seems to be forcing Matlab to end via Task Manager. The problematic commands include:

saveas % for all file types except .fig

cd % when changing to a non-existent directory, e.g. mis-typing the path.

Sometimes this makes the whole computer unusable, with other programs 'not responding' for a long time. Task Manager shows disk use at 100%, but with very little disk throughput, <100kB/s.

This didn't happen a week ago on the same machine. I haven't made any changes to Matlab, but I do accept the Windows updates pushed by Microsoft.

I tried using Matlab 2018a instead, since I still have it installed on the same machine. I did not encounter the reported problem. I then re-installed Matlab 2019a, allowing the installer to overwrite all the executable files. The problem no longer occurs.

It would appear that one or more files of the 2019a installation was corrupted.

MATLAB: Am I unable to advance past the second DVD prompt when installing MATLAB on Linux

When installing MATLAB from DVDs or disk images on Linux, each disk is mounted, and then the installer is run from the disk to install the software. When the installer prompts for a second DVD, you must unmount the first disk before removing the disk from your computer and inserting the second DVD. Failure to do so will cause the installer to be unable to detect the second DVD, and you will be unable to proceed with the installation process.

For instructions on how to mount or unmount DVDs or disk images, please see your Linux distribution's documentation, or contact your system administrator.

MATLAB: Undefined function error is very slow to occur

This is most likely due to having network locations on your MATLAB path. While connected to the internet, MATLAB searches through all of these paths before concluding that no such variable/function exists. When not connected to the internet, MATLAB is forced to ignore any network locations. To check this, you can restore the default MATLAB path. Please note that if you have custom paths that you would like to keep on your MATLAB path, you may want to back them up first. See this MATLAB Answers post for more details:

https://www.mathworks.com/matlabcentral/answers/166871-how-will-running-the-restoredefaultpath-and-savepath-commands-affect-my-custom-paths-and-how-do-i-ba

To restore the default MATLAB path, execute the following in the MATLAB Command Window and then restart MATLAB:

>> restoredefaultpath
>> rehash toolboxcache
>> savepath

If this does not correct the issue, then you may have some network locations in your history. You can clear your history by executing the following and then restarting MATLAB:

>> s = settings;
>> s.matlab.desktop.currentfolder.History.PersonalValue = {''}

You can also change the maximum size of your history, so that MATLAB will not store as many locations. To do this, execute the following code and restart MATLAB:

>> s = settings:
>> s.matlab.desktop.currentfolder.HistorySize.PersonalValue = 20; % you can adjust this value
