Simulink Library Browser doesn´t show any blocks

Hello everybody,

I just installed Matlab 2015a (academic license) and found the simulink library browser empty, besides the recently used blocks entry (which is empty). System is a Win7 Proffesional 64bit.

What can I do about it?

[Julius Durst]

I have got the same Problem with R2015a, running on arch linux 64bit.

[Tarif Fuad]

i got same problem with R2021a

[Sam Segers]

I got the same problem in the 2021 versions.

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).

I had the same problem, with no blocks appeared when opening the Simulink Library Browser. It only stated "Recently Used Blocks", but everything was empty.

I went into "Preferences" in Matlab -> "Simulink" -> "Open Simulink preferences" A new windows appears: Go to "Data Management Defaults" -> select "Simulink" as package and hit refresh.

Now I have the blocks in my library.
