Hello All,
I call an external process(.exe) from matlab on windows machine through the script using 'system()'
is their any way to findout the PID of the above called process (note : the same process may also be active apart from matlab called once i.e several instances of that application may already be active , but i am interested to only find out the PID of the process called from matlab) ?

Instead of using system(), use .NET to start the process

After that, the process ID will be the Id property of the object.

This is demo code, like you had asked for. You would need to change FileName to match the path to the exe you want to run, and need to change Arguments to any command line arguments needed.
