How to find the Process ID (PID) in matlab

Is there any function or method in matlab to find the process ID (PID) of the program in the task manager ?

Answer 1

[MathWorks Support Team]

Starting in R2025a, you can obtain the PID of a MATLAB process with the MATLAB command:

>> matlabProcessID

This function returns the PID as a uint64 variable.

In earlier versions of MATLAB, you can obtain the PID of a MATLAB process with the MATLAB command:

>> feature('getpid')

This returns the PID as a double variable. Please note that the use of the "feature" function is undocumented, meaning that it can be removed or changed at any time.

There is an undocumented (but relatively well-known) function:

   >> feature getpid

[Muharrem Askin]

Actually I would like to get the PID of another programs when they are running at the time I check it. Simply, I would not only want to get the PID of matlab but also the others listed on the task manager. Do you know how can I do that ?

[Kaustubha Govind]

I think you might need to figure out a Windows shell command that does that and use the SYSTEM function to call into the shell.

To find the running tasks: [response,tasks] = system('tasklist');

For details on tasklist, look at http://technet.microsoft.com/en-us/library/bb491010.aspx

e.g. to find Excel [response,tasks] = system('tasklist/fi "imagename eq Excel.exe"')

A .NET solution:

name = 'excel'; %for example
p = System.Diagnostics.Process.GetProcessesByName(name);
if p.Length == 1
   pid = p(1).Id; %You must index into p (not p.Id), as this changes the class type
end

pid = feature('getpid')

Try [~,result] = system('tasklist');

Since the R2025a release, you have now the matlabProcessID function.
