MatLab by Mathworks

MatLab is an analysis package used to run complex calculations and create visualizations of data created by the Mathworks company.

If you are running MatLab on a high-resolution display on a Linux OS (such as our VME machines) and the text is too small to read comfortably:

1.  Open up Matlab.

2. In the Command Window execute the following commands (press enter after each command):

     2a. s = settings;s.matlab.desktop.DisplayScaleFactor

     2b. s.matlab.desktop.DisplayScaleFactor.PersonalValue = 1.5

3. Close MatLab completely and re-open it. 

The commands above were found HERE on Mathworks' Answer Site. 

To Install MatLab (borrowed from VT's "College of Engineering" SoftWare Assistance Triage team's site) via a purchased license:

  1. Open a browser and go to Network Software ( to download MATLAB.
  2. Log in with your VT PID and password (this is NOT your FBRI password).
  3. Expand the MATLAB item in the list of software and select the latest version of MATLAB for your operating system (currently this is 2019a for Windows, Mac OSX, and Linux).
  4. Select Yes and then Accept Agreement to accept the license.
  5. Print or Screenshot the activation key as you will need it later.
  6. Select Continue.
  7. Select the link in the center of the screen that says Download
  8. The download should automatically start based on your browser's preferences. You may need to choose to save the file to your desktop or some other convenient place. If the download did not automatically start, it may have been blocked by your web-browser. If so, there may be a status notification on the bottom of the window or near the address bar that you can select to allow the download.
  9. Once the file has finished downloading, right click on the file and choose Extract all.
  10. Verify you are still connected to the internet before starting the install.
  11. Open up the extracted folder and open the file called Setup.
  12. Select the Install automatically using the Internet (recommended) and select Next to continue.
  13. If you have not installed MATLAB before:
    1. Select the Need to create a MathWorks Account button and then select Next to continue.
    2. Sign up for an account using your Virginia Tech E-mail Address. If you do not use your VT E-mail address, activation will not work.
    3. Select Next to continue.
  14. If you have installed a previous version of MATLAB, log in with your MathWorks account (VT email and MathWorks password) to continue.
    1. To reset your password go to: and enter your email. MathWorks will e-mail your password to your VT email. It may take up to an hour to receive your new password. Wait to receive the password before continuing.
  15. Enter the Activation Code from Network Software and select Next.
  16. Select the defaults for the next three screens: Select installation path, select modules to be installed (all selected by default EXCEPT License Manager), and confirm selection. Select Next to continue.
  17. Select Install when the option is available. This should take about 10 to 45 minutes depending on your system's specifications.
    1. During the installation, if a File Extension Warning dialog is shown, select Yes to All.
  18. When the installation has completed, you will need to activate MATLAB. Be sure that Activate Matlab is checked and select Activate.
  19. When the screen appears that says Provide User Name you will need to look up your the username you enter to log into your computer. Your installation will not work if you do not use the correct username.
    1. Click on Start in the bottom left hand corner of your desktop.
    2. Click on Control Panel.
    3. Click on User Accounts.
    4. Make sure the name in your MATLAB installation next to Windows User Name is the same as the current user account. For most people, this should already be correct. If it is different you will need to change the name in the Windows User Name box. Once they are the same, select Next to continue.
  20. Select Finish. Once you get the Activation is complete message, you can start using MATLAB!
