Hi,
I read the document "Using \startalign and friends" of Aditya (that it's
good) and I can't find anything under ams aligned. Is this an equivalent
in ConText?
For example, what is the equivalent of:
\begin{equation*}
\left.\begin{aligned}
& 2^2 | n_0\\
& 4^2 | n_0 + 2 \Rightarrow (2^2)^2 | n_0 +2 \Rightarrow 2^2 | n_0 +2
\text{ ya que } 2^2 | (2^2)^2
\end{aligned}\right\} \Rightarrow 2^2 | (n_0 + 2 - n_0) \Rightarrow 2^2 | 2
\end{equation*}
in ConTeXt?
I tried something like:
\startformula
\startmathalignment
\NC \startaligned
\NC \lambda_{0, \lvert k - s \rvert} (n) \NC < f(n) \NR
\NC \text{ per a $n$ suficientment gran } \NC \NR
\stopaligned \NC \iff
\startaligned
\NC \lambda_{s, k} (n) \NC < f(n) \NR
\NC \text{ per a $n$ suficientment gran } \NC \NR
\stopaligned \NR[+]
\NC \lambda_{s, k} (n) < f(n) \text{ per a $n$ suficientment gran } \NC
\iff \lambda_{0, \lvert k - s \rvert} (n) < f(n) + C \text{ per a $n$
suficientment gran } \NR[+]
\stopmathalignment
\stopformula
but " Undefined control sequence" appears to me.
Thanks a lot,
Xan.

Strictly speaking, none. You can fake aligned and gathered with matrices.

Of course. The command \startaligned is not defined. Here is one way to do
this.
\definemathmatrix[rightbrace]
[align=left,
left={\left.},
right={\right\}},
style=\displaystyle]
\starttext
\startformula
\startrightbrace
\NC 2^2 | n_0 \NR
\NC 4^2 | n_0 + 2
\Rightarrow (2^2)^2 | n_0 +2
\Rightarrow 2^2 | n_0 +2 \text{ ya que } 2^2 | (2^2)^2
\NR
\stoprightbrace
\Rightarrow 2^2 | 2
\stopformula
\stoptext
I would also use \implies instead of \Rightarrow (slightly different
spacing).
Aditya

Maybe for simple alignments the following is good enough?
\startformula
\left.\eqalign{
& 2^2 | n_0\cr
& 4^2 | n_0 + 2 \Rightarrow (2^2)^2 | n_0 +2 \Rightarrow 2^2 | n_0 +2
\text{ ya que } 2^2 | (2^2)^2
}\right\} \Rightarrow 2^2 | (n_0 + 2 - n_0) \Rightarrow 2^2 | 2
\stopformula
Olivier

Thanks Aditya and Olivier.
I will try something more difficult with these commands.
Xan.
