MATLAB: Doesn’t the ‘ver’ command list all of the products that I have installed

installMATLABtoolbox

I installed MATLAB and other toolboxes, OR I installed additional toolboxes into an existing MATLAB installation.
When I open MATLAB, the toolboxes do not show up.
When I run the "ver" command, the toolboxes are not listed.
How can I get ver to list all of my toolboxes and restore them to the MATLAB interface?

Best Answer

MATLAB stores a list of toolboxes in a cache file.
If you install a new toolbox, the cache file may not be updated.
To resolve this issue, you can update the toolbox cache file by executing the following command from the MATLAB Command Window:
    >> rehash toolboxcache
After executing this command, please restart MATLAB and execute the "ver" command again. It should now list all the toolboxes installed on your machine.
If the toolboxes are still missing, you can reset the MATLAB path by executing the following command from the MATLAB Command Window:
    >> restoredefaultpath
    >> savepath
Please note that the command above will remove any custom path. After executing this command, please restart MATLAB and run the "ver" command again. It should now list all of your toolboxes.
If you are still unable to see the toolboxes in the list, they may have not been successfully installed.
In this case, please see refer to the following support article:
