How To Completely Uninstall MATLAB on Ubuntu

Ubuntu 12

In this guide, we will walk you through the process of completely uninstalling MATLAB from your Ubuntu system. MATLAB, a high-level language and interactive environment for numerical computation, visualization, and programming, is widely used by engineers and scientists. However, if you no longer need it, you may want to uninstall it to free up system resources.

Uninstalling MATLAB via Ubuntu Software

If you installed MATLAB through the Ubuntu Software, you can uninstall it using the Ubuntu terminal. Here’s how:

  1. Open your terminal. You can do this by pressing Ctrl + Alt + T.
  2. Type the following command and press Enter:
sudo apt-get remove matlab-support

This command instructs the system to remove the MATLAB support package. The sudo command ensures you have administrative privileges, apt-get is the package handling utility in Ubuntu, and remove is the operation that uninstalls the package.

Manual Uninstallation of MATLAB

If the above method doesn’t work, you may have installed MATLAB directly from MathWorks. In this case, you will need to manually remove MATLAB. Here are the steps:

Navigate to the MATLAB Directory

Firstly, open a terminal and navigate to the directory where MATLAB is installed. This is typically located at /usr/local/MATLAB/R<version>, where <version> represents the MATLAB version you installed.

cd /usr/local/MATLAB/R<version>

Shutdown the MATLAB License Manager

If the MATLAB license manager is running, you need to shut it down using the following command:

sudo ./etc/lmdown

This command ensures that the license manager is not running, which could interfere with the uninstallation process.

Remove License Manager Files

Next, remove any license manager files in the /var/tmp directory by running:

sudo rm /var/tmp/lm_TMW*

This command removes any temporary files associated with the MATLAB license manager.

Remove the MATLAB Installation Directory

Now, you can remove the MATLAB installation directory using the rm -rf command:

sudo rm -rf /usr/local/MATLAB/R<version>

This command deletes the MATLAB installation directory and all of its contents.

Remove Symlinks to MATLAB Binaries

Finally, remove any symbolic links (symlinks) to MATLAB binaries on the path by running:

sudo rm /usr/local/bin/matlab /usr/local/bin/mcc /usr/local/bin/mex /usr/local/bin/mbuild

This command removes the symlinks to the MATLAB, MCC, MEX, and MBUILD binaries. If the deploytool symlink exists, you can remove it using:

sudo rm /usr/local/bin/deploytool

Conclusion

By following the steps outlined in this guide, you should be able to completely uninstall MATLAB from your Ubuntu system. If you encounter any issues, it is possible that there are residual files or configurations left behind. In that case, you may need to manually search for and remove any remaining MATLAB-related files or directories.

Remember to replace <version> with the actual MATLAB version you installed in all the commands. Always be careful when using commands that modify your system, such as rm -rf, as they can permanently delete files.

If you need to reinstall MATLAB or another version of it, you can visit the official MathWorks website for the latest installation packages and guides.

Can I uninstall MATLAB using the Ubuntu Software?

Yes, if you installed MATLAB through the Ubuntu Software, you can uninstall it using the Ubuntu terminal. Simply follow the steps mentioned in the guide.

What if I installed MATLAB directly from MathWorks?

If you installed MATLAB directly from MathWorks, you will need to manually remove it. The guide provides step-by-step instructions on how to navigate to the MATLAB directory and remove all relevant files and directories.
