This is a great idea, but it doesn't work on my Mac. No errors are generated, but the structure fields all come back as zero or nan. Digging into the function, I can see that the undocumented "feature" command returns the correct PID, but the subsequent awk call cannot open the file /proc/(PID)/status.
I'm running MATLAB2019a on OS X High Sierra.

Nice... it works with my Ubuntu 18.04 since the built-in MATLAB function "memory" doesn't work

Excellent, and it does work on non Windows systems. Thanks.
