Hello,
I'm trying to typeset some linear algebra exercises for my students; the
exercises will be within a table, and each second element will be a system
of linear equations. This sort of thing:
\starttable[|l|M|l|M|]
\NC (a) \NC %
\startmathalignment[n=7,align={right,middle,right,middle,right,middle,right}]
\NC 3x\NC +\NC 6y\NC -\NC 2z\NC =\NC -13\NR
\NC -6x\NC -\NC 9y\NC +\NC 5z\NC =\NC 22\NR
\NC 3x\NC +\NC 3y\NC -\NC 5z\NC =\NC -13\NR
\stopmathalignment
\NC (b) \NC %
\startmathalignment[n=7,align={right,middle,right,middle,right,middle,right}]
\NC x\NC +\NC 3y\NC +\NC 3z\NC =\NC -4\NR
\NC x\NC +\NC 4y\NC +\NC 5z\NC =\NC -5\NR
\NC 2x\NC +\NC 4y\NC +\NC 3z\NC =\NC -5\NR
\stopmathalignment
\NC\AR
\stoptable
But this doesn't work. There seems to be a problem with the mathalignment
environment within the table. What do I need enclose these in so that they
will be treated as displayed equations within the table environment? I'm
using MkII.
Thanks,
Alasdair

(Untested): \framed[align=normal,width=fit]{\startformula \startmathalignment ... \stopmathalignment \stopformula} math alignment is a display math environment, and must be inside a \startformula ... \stopformula. Two comments: 1. You know about \definemathalignment, right? 2. I think that this effect can be obtained more easily using \startitemize[two,columns,a] \item ... \item .. \stopitemize but you might need to insert a negative \vskip (or \blank) to get matrix to align with the item symbol.

I'll keep fiddling. This is one of those occasions which makes the conversion from LaTeX to ConTeXt tricky for a beginner!
