to the height of their contents, e.g., \left| expr \right| \left\{ expr \right\} \left\Vert expr \right Variable-sized symbols (displayed formulae show larger version) \sum \prod \coprod \int \oint

column (with optional characters | inserted for vertical lines) and rowj includes character & a total of (n 1) times to separate the n elements in the row Examples: \left( \begin{array}{cc} 2\tau & 7\phi-frac5{12} \\ 3\psi & \frac{\pi}8 \end{array} \right) \left( \begin{array}{c} x \\ y \end{array} \right) \mbox{~and~} \left[ \begin{array}{cc|r} & & \\ & & 729 \end{array} \right] f(z) = \left\{
