[NTG-context] Error after latest update

[NTG-context] Error after latest update

[Shiv Shankar Dayal]

I have defined a determinant environment like below:

\definemathmatrix[determinant]
                  [matrix:bars]
                  [simplecommand=thedeterminant]

and I create a determinant like below:

\startformula \startdeterminant\NC a_{11} \NC a_{12} \NC a_{13} \NC
\cdots \NC a_{1n}\NR
 \NC a_{21} \NC a_{22} \NC a_{23} \NC \cdots \NC a_{2n}\NR
 \NC a_{31} \NC a_{32} \NC a_{33} \NC \cdots \NC a_{3n}\NR
 \multispan{9}{\dotfill}\NR
 \NC a_{n1} \NC a_{n2} \NC a_{n3} \NC \cdots \NC a_{nn}
\NR\stopdeterminant

This was working before today but I updated ConTeXt and it has stopped
working. The error it gives me now is:

tex error       > tex error on line 277 in file determinants.tex: You
can't use '\Ustopmath' in restricted horizontal mode

How can I get it working again?

I never seen \multispan before. But this seems to work:

\definemathmatrix
  [determinant]
  [matrix:bars]
  [simplecommand=thedeterminant]

\starttext

\startformula
  \startdeterminant
    \NC a_{11} \NC a_{12} \NC a_{13} \NC \cdots \NC a_{1n}\NR
    \NC a_{21} \NC a_{22} \NC a_{23} \NC  \cdots \NC a_{2n}\NR
    \NC a_{31} \NC a_{32} \NC a_{33} \NC \cdots \NC a_{3n}\NR
    \HF\NR
%     \multispan{9}{\dotfill}\NR
    \NC a_{n1} \NC a_{n2} \NC a_{n3} \NC \cdots \NC a_{nn}\NR
  \stopdeterminant
\stopformula

\stoptext

I hope it gives you what you want.

Hi,

I do not remember where it came from, probably AMS Math or something like that.

Many thanks. It works but I am curious as to why the working code broke.

\multispan is a plain TeX command to create cells which span multiple 
columns
and makes only sense when you create tables with the \halign primitive 
because
tables in context use hidden cells for padding on the left and right etc.

Hi,

I still do not know why it stopped working after the latest update.

Which version was your last one you used?

Just because it worked without an error message before doesn't mean your 
input is the right  way.
Especially when you have to pass 9 as argument to \multispan even though 
you have only 5 columns
should be alarming.

The reason for the error here is that Context creates a template for 
each matrix cell which enables
and disable math mode at the begin of each cell but when you use 
\multispan the template is ignored
and you have to provide your own settings. The problem no is that no 
math mode is entered at
the begin of your new marge cell but Context always adds a end of math 
mode trigger when it reaches
the \NR command at the end of the row.

I had a copy of this older version and the cell handling was different 
back then.

Still the correct way to add filler symbols in a matrix is the \HF 
command which
has two optional commands where you can a) set the number of columns which
should be filled and b) the filler alternative to be used for the symbol.
