[NTG-context] Re: Error after latest update

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. On Tue, Aug 6, 2024 at 9:58 PM Mikael Sundqvist wrote:

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.
