The MATLAB® Engine API for Python® provides a package to integrate MATLAB functionality directly with a Python application, creating an interface to call functions from your MATLAB installation from Python code.
- MATLAB release R2024b
- Python 3.9, 3.10, 3.11, or 3.12
- Supported Python versions by MATLAB release can be found here.
MATLAB Engine API for Python can be installed directly from the Python Package Index.
$ python -m pip install matlabengine==24.2.1Prior to installation, check the default install location of MATLAB by calling matlabroot in a MATLAB Command Window. By default, Linux installs MATLAB at:
/usr/local/MATLAB/R2024b
When MATLAB is not installed in the default location, the bin/architecture directory within the MATLAB root directory must be added to the environment variable LD_LIBRARY_PATH. The path can be added to the environment variable within the shell startup configuration file (for example, .bashrc for bash shell or .tcshrc for tcsh).
# in .bashrc
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:<matlabroot>/bin/glnxa64# in .tcshrc
setenv LD_LIBRARY_PATH ${LD_LIBRARY_PATH}:<matlabroot>/bin/glnxa64MATLAB Engine API for Python can be installed directly from the Python Package Index.
$ python -m pip install matlabengine==24.2.1Prior to installation, check the default install location of MATLAB by calling matlabroot in a MATLAB Command Window. By default, macOS installs MATLAB at:
/Applications/MATLAB_R2024b.app
When MATLAB is not installed in the default location, the bin/architecture directory within the MATLAB root directory must be added to the environment variable DYLD_LIBRARY_PATH. The path can be added to the environment variable within the shell startup configuration file (for example, .bashrc for bash shell or .tcshrc for tcsh).
# in .bashrc
export DYLD_LIBRARY_PATH=$DYLD_LIBRARY_PATH:<matlabroot>/bin/maci64# in .tcshrc
setenv DYLD_LIBRARY_PATH ${DYLD_LIBRARY_PATH}:<matlabroot>/bin/maci64MATLAB Engine API for Python can be installed directly from the Python Package Index.
$ python -m pip install matlabengine==24.2.1- Start Python.
- Import the
matlab.enginepackage into the Python session. - Start a new MATLAB process by calling
start_matlab. Thestart_matlabfunction returns a Python object which enables you to pass data and call functions executed by MATLAB.
>>> import matlab.engine
>>> eng = matlab.engine.start_matlab()
>>> eng.sqrt(4.0)
2.0- Call either the
exitorquitfunction to stop the engine. Exiting Python with an engine running stops the engine and its MATLAB processes.
>>> eng.quit()See Start and Stop MATLAB Engine for Python for advanced startup examples.
You can call any MATLAB function directly and return the results to Python.
>>> eng.plus(2, 3)
5
>>> eng.isprime(37)
True
>>> eng.gcd(100.0, 80.0, nargout=3)
(20.0, 1.0, -1.0)See Call MATLAB Functions from Python for more usage examples.
