MATLAB on Ubuntu: From Install, Make launching Icon,… to Uninstall

February 12, 2012 1 comment

Here are the steps to install MATLAB + some possible problems:

  1. Extract/mount the zipped/iso installer file. For me I extract the iso to /home/bot/Downloads/Software/ml2011bu
  2. Open the terminal (Ctrl+Alt+T), type sudo sh install
    1. You might run into the problem say:Preparing installation files …
      Installing …
      eval: 1: /tmp/mathworks_2931/sys/java/jre/glnx86/jre/bin/java: Permission denied
      bot@bot-laptop:~/Downloads/Software/ml2011bu$ cd sys

      What you need to do is to make the file “java” executable by
      from your installer folder, type

      cd sys/java/jre/glnx86/jre/bin/
      chmod +x java

      you will see that the file permission is changed from
      -rw-r–r– 1 bot bot  47308 2010-10-20 04:41 java
      drwx–x–x 4 bot bot    4096 2012-02-11 17:55 java

      Now go back to the installer folder and install it with sudo sh install, and it should work

    For more details on installation, please visit

Once the installation is finished, you may want to create a script to run the MATLAB. Here is how

  1. Go to desktop (where else is fine too)
  2. Create an empty document, let’s name it
  3. Open with gedit, and type the following
    cd /usr/share/matlabr2010a/bin/
    sudo sh matlab -desktop
  4. Open the terminal, go to desktop by typing in the terminal cd ~/Desktop
  5. make the script executable by typing in the terminal chmod +x
  6. Now you can run MATLAB by running the script by typing ./

Now, if you want to add a launching icon on the menu bar, here is how:

  1. Right click on the menu bar
  2. Edit menus>Go to Programming in the left panel
  3. Click new item and add all the information
  4. In the command, type /home/bot/Desktop/
  5. You can also change the icon by clicking at the icon on the top-left corner and choose where the icon is
    1. Here is an easy command line to download the icon
      sudo wget -O /usr/share/icons/matlab.png
    2. The icon will be downloaded to /usr/share/icons/matlab.png
  6. That’s it!

And, if you are bored with MATLAB and want to uninstall it, please follow the steps here

  1. Locate the matlab dir, mine is /usr/local/MATLAB
  2. Remove the matlab dir by
    >cd /usr/local
    >sudo rm -r MATLAB
  3. bye bye MATLAB, and you get 5GB more space hahahaha!
