I try to use:
\startformula
\left\{ \begin{array}{r@=l}
xx & yy \\
zz & aa
\end{array} \right.
\stopformula
But Context log says
"Undefined control sequence \begin{array}."
How can I input multi-line equation in ConTeXt? Thanks

You can use \TeX commands such as \matrix, \pmatrix, \cases, \eqalign.

\begin{array} comes from LaTeX.

You can use \matrix from plain TeX:
\startformula
\left\{\matrix{
xx & yy \cr
zz & aa}
\right.
\stopformula
I'm not sure if there's any mechanism for automatic (right/left)
alignment. I use \hfill if necessary. (xx\hfill yy\hfill \cr ...)
