Please try to restore MATLAB and Simulink to their default states by resetting the search path, the system paths and Simulink customizations.

Before modifying the search path, you can take a backup of your 'pathdef.m' file, which can be located by using the command

>> which -all pathdef

Before proceeding, you should backup this file by copying it to a folder outside of your MATLAB path.

After backing uo, try the following commands:

restoredefaultpath
rehash toolboxcache
sl_refresh_customizations 
savepath

NOTE: This will remove any custom paths you may have created. If desired, please see the following MATLAB Answers post for how to back them up:

When I try this, I get an error message as follows:

>> sl_refresh_customizations

Unrecognized function or variable 'sl_refresh_customizations'.
