 The `jupyter-matlab-proxy` Python® package allows you to integrate MATLAB® with Jupyter®. The MATLAB integration for Jupyter enables you to open a MATLAB desktop in a web browser tab, directly from your Jupyter environment. This is not a kernel integration.
 
 The MATLAB Integration for Jupyter is under active development and you might find issues with the MATLAB graphical user interface. For support or to report issues, see the [Feedback](#feedback) section.
