    Python arguments, specified as a comma-separated list.

    MATLAB Runtime startup options, specified as a comma-separated list.

    -nodisplayOn Linux®, open the MATLAB Runtime without display functionality.
    '-logfile,filename'Write information about the MATLAB Runtime startup to a logfile.
    '-startmsg,message'Specify message to be displayed when the MATLAB Runtime begins initialization.
    '-completemsg,message'Specify message to be displayed when the MATLAB Runtime completes initialization.

    Python command to execute, specified as a character array.

    Python module to execute, specified as a character array.

    Note

    If you want to use a specific version of Python, set the PYTHONHOME environment variable on your machine to point to the parent of the directory that contains the Python interpreter for the desired Python installation prior to invoking mwpython.

    Alternatively, to use a virtual Python environment, see the MATLAB Answers™ article Python virtual environments with Python Interface.

    Note

    If you have a Python virtual environment, and it is activated, the VIRTUAL_ENV environment variable will be set to the location of your virtual environment. mwpython will check this variable and use it to find the interpreter. If you have a Python virtual environment, but it is not activated, or if you don't have a Python virtual environment, you can set the VIRTUAL_ENV to point to any virtual environment or interpreter.
