LaTeX 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

Like this?

<br /> \sigma_{3} = \left(<br /> \begin{array}{cc}<br /> 1 &amp; 0\\<br /> 0 &amp; -1<br /> \end{array}<br /> \right)<br />
