This is an exporter for nbconvert that turns matlab-notebooks into neatly formatted matlab (.m) files. You need to have nbconvert installed.
Usage: type jupyter nbconvert --to matlab 'notebookname.ipynb', inserting your filename as needed.
All cells in the resulting .m files are delimited by the matlab sectioning %%, which means you can run your code as sections in Matlab like you would in jupyter. All code cells have the heading "Cell [X]", where X is the output number present in your notebook.
You can then turn these .m files into Matlab Live Scripts, which is Mathwork's version of a notebook. In future releases, I may release something like this as well.
Install by cloning this repository, opening a terminal in the directory, and typing pip install ., or get the package from pypi by typing pip install matlab_nbconvert.
