or as autoload in one of my init.m files by


how can I check which version of Rubi I have actually loaded in the notebook?

    $\begingroup$ $RubiVersion is defined in V4.16.1.0. Does it exist in 4.15? $\endgroup$

  • $\begingroup$ @Michael, after having removed the old version, I can load 4.16 and the version command works. So it is not available in 4.15. Thanks a lot for your hint! $\endgroup$ Aug 27, 2021 at 13:24
