Hi,

I'd lik to know if it's possible to draw braces for functions with multiple definitions. Take the sign(x) function. There's a brace relating the function and the definitions. How can I do this with Brisk? Thanks?

   Could you please rephrase the question and maybe give me a short example?
   I'm not sure what the question is.

   Here you go:

   sign(x) =
     \begin{cases}
       -1 & {\rm when}\ x < 0, \\
       0  & {\rm when}\ x = 0, \\
       1  & {\rm when}\ x > 0.
     \end{cases}
