Hi everyone, a quick question: how can I deal with matrices in ConTeXt ? I tried to use what is described in the wiki as a form of dealing with the latex environment convention and importing the amsl package... \def\begin#1{% \csname start#1\endcsname} \def\end#1{% \csname stop#1\endcsname} ... \usemodule[amsl] then I tried: \begin{array}{c} a + b \\ c + d \end{array} and also, does the tex sequence \left{ work ok in ConTeXt? Thanks in advance. Regards to everyone. Jose Ignacio Marín
