launching new instances of MATLAB with COM objects

Hello all,

I am trying to launch MATLAB application using a python script (for some automation).

I use Python 2.7, MATLAB R2016B

# Python code
from win32com.client import constants, Dispatch
oMatlabObj = Dispatch("matlab.application.9.1")

It opens MATLAB and performs the automation I expect well.

But, while this automation is running, I intend to open another MATLAB instance via COM and do some other stuff.

I try to run an other python script with the above lines. But it doesn't open a new matlab instance. Instead works on the old matlab instance.

How do i force COM to open a new MATLAB instance?
