How can I get a brace on the right, not the left, to group cases, using cases? (I know actual cases look better with the brace on the left, but the items I need to group are not literally cases. They are a set of steps in an algorithm which I want to consider as an item.)

The following puts the brace on the left. All I need to do is to flip it to the right.


Thanks for any help with this!

use package mathtools. There is also a drcases environment


E = m c^2 & foo \    \int x-3\, dx & barbaz
\end{rcases*} y=f(x)

Many thanks for this! Loading mathtools and changing cases to drcases works perfectly! – Harry Macpherson Mar 10 '12 at 21:14

With the help of the aligned environment from amsmath, you can define your own environment:




  a &= b + c \\
  d &= e + f + g \\
  h &= i + j + k + l
\text{ three equations}

Hi. What can I do to have the brace on the left instead? What changed should I make? Thanks. – Steeven Nov 11 '12 at 14:09
@Steeven in that case, you don't need anything special; you can use the cases environment from the amsmath package. – Gonzalo Medina Nov 13 '12 at 22:33

Maybe something like this:


\end{aligned}\right\} = stuff

Did you read my answer? :-) – Gonzalo Medina Mar 10 '12 at 21:26
@Gonzalo yes I did now, you were faster than I. I saw your solution after having formatted my answer. Sorry. – Peter Breitfeld Mar 10 '12 at 21:29
