I would see if you can open a jupyter notebook and start a notebook with the mat lab kernel. If not, it either isn’t installed, or maybe is installed in a different jupyter.
If you get errors here, the issue is outside of org mode. For example, the hylang kernel quit working for me a while ago. See https://github.com/Calysto/matlab_kernel#kernel-times-out-while-starting for some troubleshooting tips.
