In newer versions of MATLAB, you can obtain the PID of a MATLAB process with the MATLAB command:
>> feature('getpid')
Please note that the use of the "feature" function is undocumented, meaning that it can be removed or changed at any time.
Another option would be to use the basic system commands. To get started, here are the commands to get all processes with "matlab" in their name:
% For Windows
>> [~,procs] = system('tasklist | findstr -i "MATLAB.exe"')
% For Unix
>> [~,procs] = system("ps aux | grep matlab | grep your_username")
.
NOTE: If the goal is to manage multiple MATLAB sessions for computation, we recommend using the "batch" function in the Parallel Computing Toolbox. This enables the user to run scripts and functions in the background, and it automatically returns a "parallel.Job" object that enables access to the state of the running script and the methods to control the running script.
