Dependencies

Ubuntu 20.04:

apt install libgtk2.0-0 libgbm1

• https://github.com/mathworks-ref-arch/container-images/tree/main/matlab-deps/r2023b
  • 2023b/CentOS7: glibc-langpack-en glibc-locale-source libsndfile (didn't fix it)

matlab java error

Undefined function 'usejava' for input arguments of type 'char'.

Caused by corrupted / empty / missing / wrong pathdef.m file, cased by aborted (99%) or corrupted install.

Having performed the "restoredefaultpath;matlabrc" fix mentioned above I then navigated to the C:\Program Files\MATLAB\R2011b\toolbox\local folder and typed "savepath pathdef.m". The system now appears to be working normally.
