Every time I start up MATLAB, I receive this message:
Warning: Name is nonexistent or not a directory:
C:\POSTDOC\vlfeat\toolbox\mexw32.
Warning: Name is nonexistent or not a directory:

How do I fix this?

I launched Matlab. I got a whole set of "Warning: Name is nonexistent or not a directory:" messages. I pasted in the restore path and save path commands but it would always immediately crash like in <5 seconds and go away altogether. The only thing left was the error dialog box asking to send a crah report to Mathworks which I duly did maybe half a dozen times. Pressing send or ok on that meant that went away and so I was matlab free in terms of running applications. Restarted the Mac and it had the same pathology. So, pathdef to trash and then it was fine. I now have to add back my custom paths.

@Simon Dawson, since you got an official crash report and MATLAB itself shutdown, it was a real crash and the Mathworks should be contacting you by email with some response.

METHOD #1
If there are some folders in the path you'd still like to keep on the path, and just remove the one folder that it is complaining about,
  1. Go to the "Home" tab of the tool ribbon,
  2. Click the SetPath icon.
  3. Then locate the missing folder(s) and highlight them.
  4. Click Remove, Save, and Close.
You should not see the missing folders listed the next time you start MATLAB. I think this is the preferred method.
-------------------------------------------------------------------------------------------------------------------------------------------------
METHOD #2
If you'd rather do it by fixing the file in an editor window, instead of simply doing it via the toolbar button meant for this, then you can edit pathdef.m
>> edit pathdef.m
Then search for and locate the bad folder, delete that line in the file, and save the file. You should not see the missing folders listed the next time you start MATLAB.
If NEITHER of the above two methods work, then check your startup.m file by typing "edit startup.m" on the command line. See if everything looks fine there (i.e., there are no calls to addpath with non-existent folders). If non-existent folders are added to the path in your startup.m file, remove them.
-------------------------------------------------------------------------------------------------------------------------------------------------
METHOD #3
Finally, as a last resort, you can issue the line
restoredefaultpath
savepath
to get back to initial "right out of the box" conditions just as if you'd reinstalled MATLAB. This will remove any folders that you have added to the search path after you installed MATLAB and get you back to the original default path.

Thanks. Interesting that the set path window did not contain my defective path; however, the pathdef.m file did. Simple edit and it's fixed.

>> edit pathdef.m
  • Remove the directories that are causing the error.
  • Save the file and restart matlab, you will notice that you no longer have the error.

I am having a very similar problem. I get the error below every time I start matlab. I no longer have the crp toolbox. However, the problem paths are not listed when I go to File > Set Path or in pathdef.m
restoredefaultpath savepath --> This doesn't fix the problem

Does that folder exist? Start a new question and attach your startup.m file. You're probably cd'ing to that folder and it's not there.

Oh that actually helped me solve the problem! The startup file had a couple of addpath lines to those non-existing files. Thank you very much!

I have a similar problem. When I first open MATLAB, I see those same warnings, name non existant or not a directory, but I know what's the cause. I have formatted my pc, and somehow Microsoft managed to change my computer User name from what it was previously. Now, I can't run any of my models. Can anyone help me with fixing this problem please?

Vicente, consider making a shortcut or symbolic link for the old directory name to point to your current directory name.

Open the files it tells you to and change any occurrence of "C:\Users\lenovo\MATLAB Drive" to some folder that you actually DO have.
Walter Roberson
Walter Roberson 2020-4-2
The code for some of the functions for submitWithConfiguration has some lines in which parts is a function, and also has some lines in which parts is a variable. Recent changes in the way MATLAB finds functions and variables say that when you use a single name as a function and a variable in the same routine, that MATLAB is permitted to assume that the name only refers to a variable, and then to complain when the variable does not yet exist at the time that the name was intended to be a function call. You need to edit the code so that uses some other variable name rather than parts

Warning: Name is nonexistent or not a directory: C:\Users\maila\AppData\Local\Temp\Editor_yviar
Is my error when I run Matlab. I can't understand what the problem is. And plus as I was trying to
cd ~/Desktop
mkdir CONN_Demo
To learn functional connectivity on CONN-Toolbox, I had another problem:
"Cannot CD to C:\Users\maila\Documents\~\Desktop (Name is nonexistent or not a directory)."
Could you tell me what I should do as a non-programmer user?
Thank you in advance...

For the first message see
https://www.mathworks.com/matlabcentral/answers/514545-why-do-i-get-a-warning-name-is-nonexistent-or-not-a-directory-about-the-editor_vxdxq-folder?s_tid=srchtitle
For the other part:
You appear to be going through the tutorial https://andysbrainbook.readthedocs.io/en/latest/FunctionalConnectivity/CONN_ShortCourse/CONN_02_DataDownload.html which is written expecting that the user is using Mac (or possibly Linux). You will need to replace
cd ~/Desktop
with
cd C:\Users\maila\Desktop
In the place it says
movefile('~/Downloads/sub-01_func_sub-01_task-rest_bold.nii.gz', 'sub-01/func')
movefile('~/Downloads/sub-01_anat_sub-01_T1w.nii', 'sub-01/anat')
then instead of ~/Downloads you should give the path to the place you downloaded the .nii.gz and .nii files which might possibly be
movefile('C:\Users\maila\Downloads/sub-01_func_sub-01_task-rest_bold.nii.gz', 'sub-01/func')
movefile('C:\Users\maila/Downloads/sub-01_anat_sub-01_T1w.nii', 'sub-01/anat')
for your particular account -- here the maila refers to your account name which happened to be stated in the error message about C:\Users\maila\Documents\~\Desktop

i have this error when i tried to submit my assignment on matlab.
can you find solution for this?

See https://www.mathworks.com/matlabcentral/answers/481388-how-do-i-resolve?s_tid=srchtitle for a technical explanation.
You need to get corrected code from the courseware system; if corrected code is not available, then the responses at the above link describe how to modify the code yourself.

I had the same problem. I've just open by console
open startup.m
and delete directories there. Then save the file and that's all.
