Hi, Minimal example: \definemathmatrix[pmatrix] [left={\left(\,},right={\,\right)}] \starttext Digueu quines de les matrius següents són regulars. Quan ho siguin, trobeu la inversa \startitemize[a,columns,four] \item \startpmatrix[n=2] \NC 2 \NC 3 \NR \NC 6 \NC 7 \NR \stoppmatrix \item \startpmatrix[n=3] \NC 3 \NC 2 \NC 1 \NR \NC 4 \NC 5 \NC 3 \NR \NC 5 \NC 0 \NC -2 \NR \stoppmatrix \item \startpmatrix[n=3] \NC 5 \NC 4 \NC 2 \NR \NC 2 \NC 2 \NC 3 \NR \NC 7 \NC 6 \NC 5 \NR \stoppmatrix \item \startpmatrix[n=4] \NC a \NC 0 \NC 0 \NC 0 \NR \NC 0 \NC b \NC 0 \NC 0 \NR \NC 0 \NC 0 \NC c \NC 0 \NR \NC 0 \NC 0 \NC 0 \NC d \NR \stoppmatrix \stopitemize \stoptext produces misalignment in last item (I attach pdf) Can anyone confirm that? Thanks, Xan
