Installation issue with python 3.12

Fresh env. Tried both pypi and source installation: Got the following error:

Issue resolved when reverted to python 3.10

Interesting. I didn't see that one coming. Indeed, I am using 3.10 for development. I will add that requirement in the installation section. Thanks

This issue seems to be caused by the Matlab dependency matplotlib == 3.5.0. Something about PEP517. If you upgrade the dependency to 3.6.0 it works fine on 3.12.

I'm also having this issue, this seems like an easy fix. I'll check for my sys later today.
