MATLAB silent install script

matlab-silent-install.sh

# Script to silently install MATLAB components, run as root if installing to /opt
# Requires: `license.lic`, `packages` list and `file-install-key` files

# Download license.lic and create file-install-key file from [MATLAB license centre](https://uk.mathworks.com/licensecenter/licenses)
# Download and extract latest [MATLAB installer](https://uk.mathworks.com/downloads/)
# Download packages `archive` files by running installer graphically first
# Make a package list, uncommenting lines from installer_input, `tail -87 installer_input.txt > packages`
# Check destination directories are correct below

# Destination, MATLAB installer and config files directory
dest=/opt/matlab
install=$dest/install
config=$install/cfg
# Create directories if they don't already exist
mkdir -p $dest $install $config

# Check if required files exist in current directory
