MATLAB: Menu bar missing in Simulink

disabledMATLABmenu barmissingsimulink

I installed an academic licanse of MATLAB R2016b and Simulink on my new computer a couple of days ago and started working on a simulink project and everything was going fine. However when I opened the simulink model today the toolbar was missing. See figure.

I have tried rebooting matlab and my system (windows 10 64-bit) which did not help, as well as googling the issue, but have not found any conclusive answers. If anyone knows how to fix this problem it would be much appriciated.

Best Regards

Viktor

Follow these steps:

1. Refresh the file system caches using the following commands:

>> restoredefaultpath
>> rehash toolboxcache

2. Run the following command to rebuild Simulink and Library menus and toolbars:

>> sl_refresh_customizations

3. Close all the instance of MATLAB and then restart.

Maybe your MATLAB install's path or toolbox cache got corrupted. If you try run the following commands in MATLAB and try opening the Library Browser again, what do you see?

>> restoredefaultpath
>> rehash toolboxcache

Then, you can refresh the library browser by pressing right-clicking and selecting "Refresh Library Browser" (or hitting F5 on Windows).

MATLAB: Refresh function and sytem path cache

The "restoredefaultpath" function restores search path to its factory-installed state. To refresh function and file system path caches please use “rehash” function and "_sl_refresh_customizations_"

>> rehash toolbox

>> rehash toolboxcache

>> sl_refresh_customizations

sl_refresh_customizations Refreshes Simulink menu and dialog customizations.
