Hello,
To resolve this issue, please follow these steps:
1) At the MATLAB Command Window, execute the following commands:
>> restoredefaultpath
>> rehash toolboxcache
>> matlabrc
>> savepath
- These commands will cause a new file, "pathdef.m", to be created.
- You should now be able to relaunch MATLAB without seeing those warning / error messages.
Another troubleshooting step is:
2. This can occur if you do not have write permissions on the folder where MATLAB is installed.
To resolve this issue, open terminal and run the appropriate command to recursively change the user's permissions on the MATLAB folder to read/write/execute:
sudo chmod -R 755 ./MATLAB
Use the above mentioned method on any Unix/Linux based operating system.
For windows, please refer to the below mentioned link:
