Hi,
i wrote some code that in the first line read data from a csv and the process it.
I tested the code under window with Matlab R2022b and it's fine, it works as expected.
Using it on linux return this error:
% WITHOUT A PATH
>> readmatrix()
Error using readmatrix
Invalid default value for property 'Options' in class 'matlab.io.internal.functions.AcceptsImportOptions':
Error: File: ImportOptions.m Line: 731 Column: 20
Unable to find or import 'matlab.io.internal.common.display.cellArrayDisp'. Imported names must end with '.*' or be fully qualified.
% WITH A CORRECT PATH
path = strcat('src\Calibration\MagneticSesonsors\MagneticSensorsCSV\BigSensorsCSV\Calibration\MagneticAndUWB\WA0000',num2str(2),".CSV")
path =
"src\Calibration\MagneticSesonsors\MagneticSensorsCSV\BigSensorsCSV\Calibration\MagneticAndUWB\WA00002.CSV"
>> readmatrix(path);
Error using readmatrix
Invalid default value for property 'Options' in class 'matlab.io.internal.functions.AcceptsImportOptions':
Error: File: ImportOptions.m Line: 731 Column: 20
Unable to find or import 'matlab.io.internal.common.display.cellArrayDisp'. Imported names must end with '.*' or be fully qualified.
both with a correct string path argument that without it.
It is a problem of my installation? i've already update to the last release and already try to reinstall Matlab. Can anyone help me to understand and fix it?
NOTE: The .csv files are not open during the commands execution.

Unfortauntely Valerio I haven't been able to reproduce this issue. I am able to use the readmatrix() function on a (.csv) file referenced by a path on a Linux OS (Ubuntu 20.04.5 LTS). So I think there may be an issue with how MATLAB is installed/setup.
Since you already re-installed MATLAB, I would try restoring your MATLAB path to the default. This can help uncover if there is a path issue, shadowing issue or possibly a corrupt installation. Note that running these commands will remove any custom paths you have made, so look at this other post for some information on how to back them up: https://www.mathworks.com/matlabcentral/answers/166871-how-will-running-the-restoredefaultpath-and-savepath-commands-affect-my-custom-paths-and-how-do
Try these in your MATLAB Command Window (after making a backup if you have a custom path!):
>>restoredefaultpath
>>rehash toolboxcache
>>savepath
If you are still experiencing issues, I'd then recommend contacting MathWorks Technical Support

UPDATE: after io reinstall again MATLAB, i notice that at the startup in the command Window there are a lot of warnings:

Maybe is this the problem?
