The Challenge of Opening Matlab on Ubuntu

Before we delve into the methods, let’s understand the challenge we are trying to address. Opening Matlab on Ubuntu can be a bit tricky, especially if you are new to the Linux environment. Unlike on Windows or macOS, there is no shortcut or start menu entry to directly launch Matlab.

However, worry not! We have got you covered with multiple methods to open Matlab on Ubuntu. Let’s explore each method in detail.

Video Tutorial:

Method 1: Using Terminal

Method Explanation

The first method involves launching Matlab using the terminal. This method is straightforward and provides direct control over the Matlab process.

Steps to Open Matlab Using Terminal

1. Open the terminal by pressing Ctrl+Alt+T simultaneously.
2. Navigate to the directory where Matlab is installed using the `cd` command. For example, if Matlab is installed in the `/usr/local/MATLAB/R2020a` directory, enter the following command: `cd /usr/local/MATLAB/R2020a`.
3. Once you are in the Matlab installation directory, run the command `./matlab` to open Matlab.

Pros:
1. Allows for direct control over the Matlab process.
2. Can be easily automated using scripts or aliases.
3. Provides access to verbose information through terminal logs.

Cons:
1. Requires manual opening through the terminal.
2. Inconvenient if you want to use the graphical user interface without the terminal.

Method 2: Using Desktop Shortcut

Method Explanation

The second method involves creating a desktop shortcut for Matlab. This method provides a convenient way to launch Matlab directly from the desktop, similar to how it is done on Windows or macOS.

Steps to Open Matlab Using Desktop Shortcut

1. Right-click on an empty area of the desktop and select "Create Launcher" or "Create New Launcher".
2. In the launcher properties dialog, provide a name for the launcher (e.g., "Matlab") and select the Matlab icon.
3. In the "Command" field, enter the path to the Matlab executable file. For example, if Matlab is installed in the `/usr/local/MATLAB/R2020a` directory, enter the following command: `/usr/local/MATLAB/R2020a/bin/matlab`.
4. Save the launcher, and you should now have a desktop shortcut to open Matlab.

Pros:
1. Provides a convenient way to launch Matlab from the desktop.
2. Can be customized with a specific icon for easy identification.
3. Eliminates the need to open the terminal every time.

Cons:
1. Requires manual creation of the desktop shortcut.
2. Limited control over the Matlab process compared to opening via the terminal.

Method 3: Using Unity Dash

Method Explanation

The third method involves utilizing Unity Dash, a popular graphical user interface launcher in Ubuntu. This method provides a visually appealing way to open Matlab and can be especially useful for those who prefer a more visual approach.

Steps to Open Matlab Using Unity Dash

1. Press the Super key (Windows key) on your keyboard to open Unity Dash.
2. Type "Matlab" in the search bar.
3. Click on the Matlab icon in the search results to launch the application.

Pros:
1. Provides a visually appealing and user-friendly way to open Matlab.
2. Requires minimal effort to locate and launch Matlab.
3. No need to remember commands or navigate directories.

Cons:
1. Unity Dash search results may not always be accurate.
2. Relies on the Unity Dash interface, which may not be available in other Ubuntu variations.

Method 4: Adding Matlab to Application Menu

Method Explanation

The fourth method involves adding Matlab to the application menu, similar to how other software applications are listed. This method provides quick access to Matlab through the application menu, making it easily discoverable.

Steps to Add Matlab to Application Menu

1. Open the file manager and navigate to the `/usr/share/applications` directory.
2. Right-click in the directory and select "Create New Document" -> "Empty Document".
3. Name the new file, making sure to end it with the `.desktop` extension. For example, `matlab.desktop`.
4. Open the file using a text editor and add the following content:

"`
[Desktop Entry] Encoding=UTF-8
Name=Matlab
Comment=Matlab Launch Icon
Exec=/usr/local/MATLAB/R2020a/bin/matlab
Icon=/path/to/matlab/icon.png
Terminal=false
StartupNotify=true
Categories=Development;Math;
"`

Replace `/usr/local/MATLAB/R2020a/bin/matlab` with the actual path to the Matlab executable and `/path/to/matlab/icon.png` with the path to an image file for the Matlab icon.

5. Save the file and close the text editor.
6. Restart the Ubuntu session, and Matlab should now be listed in the application menu.

Pros:
1. Provides easy access to Matlab through the application menu.
2. Enables you to customize the icon for easy identification.
3. Incorporates Matlab into the system’s application launching process.

Cons:
1. Requires manual creation of the `.desktop` file.
2. Restarting the Ubuntu session is necessary for the changes to take effect.

Alternatives: What to Do If You Can’t Open Matlab

If you encounter any issues or are unable to open Matlab using the methods mentioned above, here are a few alternatives you can consider:

Alternative 1: Reinstall Matlab

If none of the methods work, there may have been an issue during the installation process. In such cases, it is recommended to uninstall and reinstall Matlab to ensure a clean installation.

Alternative 2: Consult Matlab Documentation

The MathWorks, the company behind Matlab, provides comprehensive documentation and support for their software. If you are facing difficulties, their documentation and online resources can be a valuable source of information and assistance.
