Hello,

I know it's a bit late, but I just used the following on Linux:

    [tmp pid] = system('pgrep MATLAB');
    [tmp mem_usage] = system(['cat /proc/' strtrim(pid) '/status | grep VmSize']);
    fprintf("%i MB\n", round(str2num(strtrim(extractAfter(extractBefore(mem_usage, ' kB'), ':'))) / 1000));

The system command executes a shell command where I first get the process ID and used the ID to get the memory usage using cat to read the process status file, then I format it and output it in MB. You can probably retrieve the PID inside the same bash command then you call the system function only once.
