[NTG-context] Math: Matrix question

2006-06-15 Thread Tobias Burnus 
Hello,

maybe someone has an idea how to typeset the following

c d
 a [E F]
 b [G H]

Where EFGH is a matrix surrounded by ( ) and with a b c d I want to
label the columns and rows.
I especially struggle with aligning c and d and having the parenteses.

Any ideas are highly welcome.

Hi Tobias,

Probably it is possible to do want with mathalign stuff developped in  
ConTeXt, but the following gives a reasonable result (using only  
Plain TeX commands...):

$$\eqalign{
\matrix{ \hphantom{\left({E}\right.} c  d \cr} \cr
\matrix{
a\cr
b\cr}\; \pmatrix{
E  F \cr
G  H \cr} \cr
}$$

\bye

Best regards: OK

Well, this was the work-around I used, however, if I replace E by
, then the alignment gets lost.
(I worked around with \,\\quad\qquad etc., but this is not so nice.)

Plain tex provides \bordermatrix. Not configurable, but will suit your 
needs.

\startformula
\bordermatrix{
   a  b  c  d \cr
   e  f  g  h \cr
   i  j  k  l \cr}
\stopformula
