Install MATLAB Engine API for Python
To start the MATLAB® engine within a Python® session, you first must install the engine API as a Python package. For other requirements, see System Requirements for MATLAB Engine API for Python.
Verify Your Configuration
Before you install, verify your Python and MATLAB configurations.
Check that your system has a supported version of Python and MATLAB R2014b or later. For more information, see Versions of Python Compatible with MATLAB Products by Release.
To check that Python is installed on your system, run Python at the operating system prompt. Make sure that the Python path is included in your system path environment variable.
Add the folder that contains the Python interpreter to your path, if it is not already there.
Install Engine API
You can install MATLAB Engine API for Python using the
pip command or a Python setup script
Starting with MATLAB R2022b, you can use the
pip command to install
the API. Choose one of the following procedures and execute from the system
To install from the MATLAB folder, on Windows® type:
cd "matlabroot\extern\engines\python" python -m pip install .
Install the engine API from https://pypi.org/project/matlabengine with the command:
python -m pip install matlabengine
MATLAB provides a standard Python
setup.py file for building and installing the engine using
setuptools. For platform-specific commands, see Python Setup Script to Install MATLAB Engine API.
Start MATLAB Engine
Start Python. Type these commands from the Python prompt to import the MATLAB module and start the engine:
import matlab.engine eng = matlab.engine.start_matlab()
For more information, see Start and Stop MATLAB Engine for Python.
Troubleshooting MATLAB Engine API for Python Installation
Make sure that your MATLAB release supports your Python version. See Versions of Python Compatible with MATLAB Products by Release.
Make sure that you have sufficient privileges to execute the install command from the operating system prompt. On Windows, if necessary, open the command prompt with the Run as administrator option.
You must run the Python install command from the specified MATLAB folder. For detailed instructions, choose one of the platform links in Install Engine API.
python setup.py install
The installer installs the engine in the default Python folder. To use a nondefault location, see Install MATLAB Engine API for Python in Nondefault Locations.
If you installed the package in a nondefault folder using
--prefix, make sure to set the
PYTHONPATHenvironment variable. For example, suppose that you used this installation command:
python setup.py install --prefix="matlab22aPy39"
In Python, update
PYTHONPATHwith this command:
