Programmatically ejecting an external hard drive

I'm currently running long scripts using data stored on multiple external hard drives connected via USB. My computer is smartcard-only, meaning that whenever I leave a script running and come back a while later, I have to "yank out" one of the cables in order to get back in. Often however the script actually finished hours before!

I'm wondering if there's a way to include an "eject hard drive" command at the end of the script. I did some searching of keywords and can't tell if this is possible in Matlab, or how to do so.

you can combine matlab's system() function with the answer of

This works perfectly, thank you. The final code is a one-liner -- on a Mac, it's

system('diskutil eject MyExternalDrive')

my bad, i assumed you are on a windows system ;)
