Displaying a Matrix-Vector Eq with LaTeX

[kimspg]

A bit OT, I know, but there must be a way to get matrices to appear on the same line so I can write matrix-vector equations.

[matt grime]

matrices can usually be displayed with an array argument, plus some bracketing argument

[chroot]

Like this?


\sigma_{3} = \left(
\begin{array}{cc}
1 & 0\\
0 & -1
\end{array}
\right)
