Math & Science ⇒ Reversed cases

[bkarpuz]

I see! You also have to change cases to rcases for the call to \matrix@check, modify this line:

Code: Select all

\matrix@check\rcases\env@rcases

Now I remember the mathtools package provides an rcases environment for exactly this purpose. So, instead of our redefinition, loading mathtools is sufficient:

Code: Select all

\usepackage{mathtools}

Thanks again Stefan! I think I can now figure out redefining new commands using the existing ones.
