    /* This DevContainer configuration demonstrates
        1. Building image from Dockerfile from mathworks-ref-arch/matlab-dockerfile
        2. Installation of MATLAB Integration for Jupyter & JupyterLab
        3. Configuration of VSCode environment for following modes of access:
            a. MATLAB in a Browser
            b. Directly from VSCode, using the MATLAB extension for VSCode
            c. Using Jupyter Notebooks in VSCode
            d. Start Codespace in Jupyter
