You can try to troubleshoot the issue by following the steps below:
- Before modifying the search path, it is important to take a backup of your 'pathdef.m' file, which can be located by using the command:
>> which -all pathdef
Before proceeding, ensure that you make a safe copy of the file by copying it to a folder outside of your MATLAB path.
- After taking the backup, please execute the following commands in the MATLAB Command Window to restore the default MATLAB search path and rehash the toolbox cache:
>> restoredefaultpath
>> rehash toolboxcache
- After this step, please use MATLAB/Simulink to see if the issue occurs again. If the issue is resolved, then you may want to save the new MATLAB search path by executing the following command:
>> savepath
NOTE: This will remove any custom paths you may have created. The following MATLAB Answers post is an additional resource on how to back them up:
