The Ubuntu Linux is one of the most popular distributions to run Matlab on *nix systems. However, the Unity launcher used by Ubuntu does not support Matlab by default and putting a shortcut to Matlab is a confusing and non-trivial task. This tutorial demonstrates an easy and straight-forward way to integrate Matlab with Unity in Ubuntu.
The powerful scientific computing tool, Matlab (Matrix Laboratory) from Mathworks is certainly a widely used tool in the scientific world. While Mathworks does provide good Windows, Linux, *nix, Mac OS X support for Matlab out-of-the-box, one overlooked aspect is the integration of Matlab to the Unity launcher used in Ubuntu.
Most users will find the installation process itself smooth across all platforms (kudos to Mathworks), however, the Ubuntu user will quickly after the installation wonder how on earth they are supposed to launch Matlab, as it does not show up on the Unity launcher bar and does not show up either when searching for it through the Unity lenses. While it is of course possible to use the terminal to launch Matlab through, for example,
$ matlab -desktop
$ /usr/local/MATLAB/R201Xa/bin/matlab
this approach is certainly not optimal, and most definitely rhymes badly with the user-friendliness of Ubuntu. Fortunately, integrating Matlab with Unity in Ubuntu can be made relatively easy by following these steps:
- Make sure that the Matlab binary already has a symbolic link in your default path by typing the following into a terminal:
$ sudo ln -s usr/local/MATLAB/R201Xa/bin/matlab /usr/local/bin/matlab
obviously by replacing the capital X in "R201Xa" with the proper path.
- Make Unity launcher in Ubuntu aware of Matlab by creating the hard link:
$ sudo ln /usr/share/app-install/desktop/matlab-support:matlab.desktop /usr/share/applications/matlab.desktop
- Edit the /usr/share/app-install/desktop/matlab-support:matlab.desktop file with your favourite text editor which will show:
[Desktop Entry]
X-AppInstall-Package=matlab-support
X-AppInstall-Popcon=3
X-AppInstall-Section=multiverse
Version=1.0
Type=Application
Terminal=false
Exec=matlab -desktop
Name=MATLAB
Icon=_usr_share_icons_hicolor_48x48_apps_matlab
Categories=Development;Math;Science
Comment=Scientific computing environment
StartupNotify=true
StartupWMClass=com-mathworks-util-PostVMInit
X-Ubuntu-Gettext-Domain=app-install-data - Change the following (marked in red above) two lines to be:
Terminal=true
Icon=/usr/share/app-install/icons/_usr_share_icons_hicolor_48x48_apps_matlab.png
After saving the above file, Matlab will be fully integrated and appear in the Unity launcher. Thus, it is possible to use the lenses to find the installed Matlab application (Meta/Windows-key+A) and also to lock the Matlab icon to the launcher by right clicking on it when it is running. Of course, it is also still possible to launch Matlab from the terminal and then lock it to the launcher if one so wishes!
Hey,
ReplyDeleteThe launcher is still not visible.
Hmm strange, did you try and restart Unity?
DeleteThanks,
ReplyDeleteBut that didn't work for me either on Ubuntu 14.04
The following worked in my launcher file:
#!/usr/bin/env xdg-open
[Desktop Entry]
Type=Application
Icon=/usr/share/app-install/icons/_usr_share_icons_hicolor_48x48_apps_matlab.png
Name=MATLAB R2015a
Comment=Start MATLAB - The Language of Technical Computing
Exec=matlab -desktop
Categories=Development;
Worked for me.
ReplyDeleteThanks very much, after my Win10 crashed and wiped all the data i am trying to move into Ubuntu. So far so good.
Thanks, finally managed to have a proper launch icon
