The "normal" matlab install doesn't work on the current anDREa Ubuntu image because the home folder uses special characters (@), unzip is not installed and mathworks.com is blocked:

This is a workaround:

Requirements:

• Advanced Member in anDREa
• A Mathworks account with an active personal license
• i.e. this doesn't work for installing matlab for Standard Members in anDREa, You would need to distribute a license file or connect to your license server which results in a very different installation procedure.
• (Temporarily) whitelisted domains in anDREa
• mathworks.com
• archive.ubuntu.com
• Unzip installed:
• Install unzip with
• 

  sudo apt install unzip
• root added to the xhost server:
• 

  sudo xhost +SI:localuser:root

Installation:

• Open www.mathworks.com in the browser of the anDREa ubuntu machine
• Open the matlab option in the tile button (top right)
• Click Install Matlab and download for Linux
• The zip file is downloaded in your Downloads folder
• Unzip the zip file
• And run
• 

  sudo ./install
• This workaround (with sudo) doesn't create the "normal" Matlab icon. Run matlab (without sudo) from terminal.
