Setup

Install MATLAB Engine API for Python

To use MATLAB Engine API for Python^®, you need to have both installed on the system. Install the engine API as a Python package.

Install Using pip

From the system prompt: 

$ python –m pip install matlabengine

Install Using setup.py

Run the setup.py file from the system prompt:

$ cd [matlabroot]/extern/engines/ python
 $ python setup.py install

For troubleshooting, ensure privileges (run as administrator) and check the PYTHONPATH and system paths. 

MATLAB Engine API

Use MATLAB Engine API to call MATLAB from Python.

Import the module and start the engine:

>>> import matlab.engine
>>> eng = matlab.engine. start _ matlab() 

Call functions through the engine:

>>> x = eng.sqrt(42.0) 

Capture multiple outputs:

>>> x = eng.gcd(42.0,8.0,nargout=3) 
>>> x = eng.plot(x,y,nargout=0) 

Stop the engine:

>>> x = eng.exit()

Data Type Conversions

Data types will be automatically converted where possible.

You can create MATLAB arrays in Python to pass data easily to MATLAB functions:

>>> x = matlab. double([1,4,9])

Using MATLAB Apps

Use MATLAB Engine Workspace

The MATLAB engine workspace can be used to access variables from MATLAB and Python and facilitates app use.

Add a variable to the workspace:

>>> x = 4.0 >>> eng.workspace['y'] = x 

Access the variable from the MATLAB workspace:

>>> x = eng.workspace['y'] 

Execute statements using the eval function:

>>> a = eng.eval('sqrt(y)') Y

ou can open apps in MATLAB from Python by using the command for the app:

>>> eng.signalAnalyzer() 
>>> eng.classificationLearner()

Create Python Package

Package MATLAB Functions Use the Library Compiler app to create a Python package for MATLAB functions.

Invoke MATLAB functions from the Python package

>>> import PackageName 
>>> pkg = PackageName. initialize() 
>>> result = pkg.Foo() 

Close Package

>>> pkg.terminate()

MATLAB in Other IDEs

You can use MATLAB from Jupyter® or VSCode.

Install MATLAB Integration for Jupyter

For example, install the package to execute MATLAB from Jupyter.

$ python pip install jupyter-matlab-proxy 
$ install-matlab-kernelspec 

Now you can use MATLAB in a browser or run code in your notebook with the MATLAB kernel.
