How can I keep a function operating while the screen is locked?

using MATLAB 2014A on macOS 10.11.6, I am running a function from the command line, and when I lock the screen the function suspends activity until I unlock it again.

Not sure if this is possible; however, if your goal is to have the function run even when your computer naturally goes to sleep/lock screen, then you can always adjust your computer settings to never sleep.

In OS-X System Preferences, Energy Saver, Power Adapter, increase your Computer sleep time.

I think the question is unclear: does 'locked' mean 'sleep mode' or 'locked' as in 'you need a password to unlock this computer'?

For the first meaning, increasing (or disabling) sleep mode in Windows would do. If the computer goes to sleep mode, all programs stop running. For the second meaning, you can lock the computer and MATLAB will still be running. On Windows, you lock the computer by pressing Win+L. For OS-X or Linux computers, I am sure there is something similar.
