Start and Stop MATLAB Engine for Python
Start MATLAB Engine for Python
Start Python® at the operating system prompt.
matlab.enginepackage into your Python session.
Start a new MATLAB® process by calling
start_matlabfunction returns a Python object,
eng, which enables you to pass data and call functions executed by MATLAB.
import matlab.engine eng = matlab.engine.start_matlab()
Run Multiple Engines
Start each engine separately. Each engine starts and communicates with its own MATLAB process.
eng1 = matlab.engine.start_matlab() eng2 = matlab.engine.start_matlab()
Call either the
exit or the
If you exit Python with an engine still running, then Python automatically stops the engine and its MATLAB process.
Start Engine with Startup Options
Start the engine and pass the options as an input argument string to
matlab.engine.start_matlab. For example, start MATLAB with the desktop.
eng = matlab.engine.start_matlab("-desktop")
You can define multiple startup options with a single string. For example, start
the desktop and set the numeric display format to
eng = matlab.engine.start_matlab("-desktop -r 'format short'")
You also can start the desktop after you start the engine.
import matlab.engine eng = matlab.engine.start_matlab() eng.desktop(nargout=0)
Start Engine Asynchronously
Start the engine asynchronously. While MATLAB starts, you can enter commands at the Python command line.
import matlab.engine future = matlab.engine.start_matlab(background=True)
Create the MATLAB instance so you can perform computations in MATLAB.
eng = future.result()
