Using \left\{ and \right\} on multiple lines
|
|
|
| TeXnicians,
I cannot seem to get the larger braces to span across multiple lines. A
minimal example:
\begin{multline}
\frac{\Delta\frac{\partial
\E(y_j|\mathbf{x})}{\partial\text{Premiu
m}}}{\Delta \text{Cover}} =
(\hat\beta_{j1} + \hat\beta_{j4} + \hat\beta_{j5})\phi\left\{
(\hat\beta_{j0} + \hat\beta_{j2} + \hat\beta_{j3}) + \\
(\hat\beta_{j1} + \hat\beta_{j4} +
\hat\beta_{j5})\times\text{Premium} +
\hat\beta_{j6}\text{Experience} + \hat\beta_{j7} \text{NCD} \right\} \\
-
(\hat\beta_{j1} + \hat\beta_{j5})\phi\{(\hat\beta_{j0} +
\hat\beta_{j3}) + (\hat\beta_{j1} +
\hat\beta_{j5})\times\text{Premium} \\ +
\hat\beta_{j6}\text{Experience} + \hat\beta_{j7} \text{NCD} \}
\end{multline}
gives errors. Using "normal" sized { and } looks ugly because of the
numerous parentheses.
Any suggestions?
Thanks

| The above wasn't really a minimal example.
Here's another one:
\begin{multline}
\phi\left\{ a + b + c \\
+ d +e +f \right\}
\end{multline}

I suggest you read up on what a minimal example is. It is something
that is supposed to pass through LaTeX, and that is hard to do without
a document preamble.

multline wasn’t designed for this, it is for breaking long equations.
You want to either use a matrix, or aligned or gathered, see amsldoc.pdf
\begin{equation}
\phi \left\{\begin{aligned}
& a & + b & + c \\
& + d & +e & + f
\end{aligned}\right\}
\end{equation}
Untested.
But I think you really don’t need big braces here.

You should do it like this:
\begin{multline}
\phi\left\{ a + b + c \right. \\
\left. + d +e +f \right\}
\end{multline}

Each line is a group, and the formula between \left and \right
is also a group.
These groups interleave rather than nest, and that is
the cause of your problem.
You've effectively got something like
[ { ] [ } ]
By the way, interleaved grouping is one of the classic
gotchas in typesetting. Italic (or coloured) text
being broken by a page boundary, for example.
To solve you're problem, you'll have to size the braces
by hand, using \bigl and \bigr, or some variant of these
commands. See LaTeX Companion, page 504.

You have to fake this yourself. An empty delimiter, ".", is there
exactly for this purpose. Thus you will have
\left\{ \text{whatever} \right. \\
\left. \text{whatever else} \right\}
Sometimes whatever and whatever else have different heights, so you
may want to include a \vphantom{the taller of the two} in the other
one. At least that's how I did it in the past...

No, no, it was programmed in Forth. See Genesis 1:12:
"And the earth brought Forth ..."

| Thank you so much for the helpful replies.
I have also found another way, if anyone is interested.
I've found that using \Bigg\{ and \Bigg\} works on equations spanning
on multiple lines.
Thanks again.

Indeed; this was Jonathan Fine's suggestion. What you're doing telling
LaTeX what size the braces should be, rather than telling it to size
them automatically as \left\{ and \right\} do.
There are four possible sizing commands in the set: \big, \Big, \bigg,
and \Bigg.
Also, note that to get the correct spacings, you should append an "l"
and an "r" to the command names: \Biggl\{ and \Biggr\}.

I used the following recently quite successfully :-
$ % Enter math mode
\left\{ % Left bracket
\begin{array}{l}
\makebox{First Line}\\
\makebox{Second Line}\\
\makebox{Third Line}\\
\makebox{Fourth Line}\\
\makebox{Fifth Line}\\
\end{array}
\right\} % Right bracket
\makebox{Text to the right of the right brace}
$ % Finished with math mode
The \left\{ can be replaced by \left. if the left brace is not
required, and likewise \right\} by \right. if the right isn't to be
used.
