TeX provides primitives called -<code>\</code><code>left</code> and <code>\</code><code>right</code>, which can be used to modify brackets (of -whatever sort) around a mathematical expression, as in: - -<code>\</code><code>left(</code><code> <expression> </code><code>\</code><code>right)</code> — the size of the -parentheses is matched to the vertical extent of the expression. -<p/>However, in all sorts of mathematical enterprises one may find oneself -needing a <code>\</code><code>middle</code> command, to be used in expressions like -<blockquote> -<pre> -\left\{ x \in \mathbb{N} \middle| x \mbox{ even} \right\} -</pre> - -</blockquote><p> -to specify the set of even natural numbers. The -<a href="FAQ-etex.html">e-TeX system</a> -defines just such a command, but users of Knuth’s original need some -support. Donald Arseneau’s <i>braket</i> package provides commands -for set specifications (as above) and for Dirac brackets (and bras and -kets). The package uses the e-TeX built-in command if it finds -itself running under e-TeX. -<dl> -<dt><tt><i>braket.sty</i></tt><dd><a href="http://mirror.ctan.org/macros/latex/contrib/braket.zip">macros/latex/contrib/braket</a> (or <a href="http://mirror.ctan.org/macros/latex/contrib/braket/">browse the directory</a>); <a href="http://mirror.ctan.org/help/Catalogue/entries/braket.html">catalogue entry</a> -</dl> -<p/><p>This question on the Web: <a href="http://www.tex.ac.uk/cgi-bin/texfaq2html?label=braket">http://www.tex.ac.uk/cgi-bin/texfaq2html?label=braket</a> -</body> |
