Dear Bruce,
i have just tried your example , but it is not working.
\startformula \startmathmatrix [fences=parenthesis] \NC \GL[1][t]\GL[1][b] \NC a \NC b \NC c \NC d \NR \NC \GL[2][t] \NC a \NC b \NC c \NC d\NC \GL[2][t]\GL[2][b]\NR \stopmathmatrix \stopformula \stoptext
After compiling I got :
1 \startformula 2 \startmathmatrix 3 [fences=parenthesis] 4 >> \NC \GL[1][t]\GL[1][b] \NC a \NC b \NC c \NC d \NR 5 \NC \GL[2][t] \NC a \NC b \NC c \NC d\NC \GL[2][t]\GL[2][b]\NR 6 \stopmathmatrix 7 \stopformula 8 \stoptext 9 10 11 The control sequence at the end of the top line of your error message was never \def'ed. You can just continue as I'll forget about whatever was undefined. mtx-context | fatal error: return code: 1
Many thanks
Uschi
The example Bruce gave works here. Do you have a (very) old version of ConTeXt? /Mikael
