 - When you execute MATLAB code in a notebook for the first time, enter your MATLAB license information in the dialog box that appears. See [Licensing](https://github.com/mathworks/matlab-proxy/blob/main/MATLAB-Licensing-Info.md) for details. The MATLAB session can take a few minutes to start.
 - Multiple notebooks running on a Jupyter server share the underlying MATLAB process, so executing code in one notebook affects the workspace in others. If you work in several notebooks simultaneously, be aware that they share a workspace. 
 - With MATLAB R2022b and later, you can define a local function at the end of the cell where you want to call it:
