Python Libraries in MATLAB
You can access Python libraries directly from MATLAB by adding the py. prefix to the
Python name. To call content in the Python standard library, add py. in front
of the Python function or class name. To call content in available modules, add
py. in front of the Python module name followed by the Python function or class name. For
example:
py.list({'This','is a','list'}) % Calls built-in function list
py.textwrap.wrap('This is a string') % Calls wrap function in module textwrapYou do not need to import modules in order to use them. However, you may import Python names into your MATLAB function in the same way that you can import content in MATLAB packages. For more information, see Understanding Python and MATLAB import Commands.
If instead you want to call MATLAB functions from Python applications, see Calling MATLAB from Python for more information.
