MarsSeed [1] filed a deletion request for matlab-dummy [2]: Unused and not useful dummy package from 2020. It also depends on broken, unmaintained legacy libraries. AUR has a proper matlab package which is kept up-to-date with upstream releases. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/matlab-dummy/
