A matrix can be described as a rectangular array of numbers, symbols or expressions that are arranged in rows and columns. So, it is not expected that all constructions written in AMS LaTeX will work here. An example is: x=v+6b¡f(3) = (p+q)(p¡q) (4) =p2¡q2(5) which was produced using the eqnarray environment: 3. Open source and XHTML compliant. Système. However, there is another statement, the matrix declaration, slightly easier to use: \begin{matrix} x & y \\ z & v \end{matrix}. The amsmath package provides commands to typeset matrices with different delimiters. Thanks.
