mathalignment within a table - help needed!
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 -- Blog: http://amca01.wordpress.com Web: http://bit.ly/Alasdair Facebook: http://www.facebook.com/alasdair.mcandrew

(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.

Thanks, the framed bit is fine, except that the base of the frame is aligned
with the exercise number "(a)", whereas I'd like the top line of the
equations aligned with the (a)...
I'll keep fiddling. This is one of those occasions which makes the
conversion from LaTeX to ConTeXt tricky for a beginner!
Thanks again,
Alasdair

Play around with: \framed[location=high|top|low|bottom|lohi|middle] Aditya
Hi Aditya see attached file ... when we upgrade the alignment code we need to look into this as well (wraping in startformula works ok but has too much spacing, but we can handle that) Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
