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

Looks like a bug; adding blank rows works around the problem (but
looks terrible):
\definemathmatrix[pmatrix] [left={\left(\,},right={\,\right)}]

not a bug ...
(1) the matrix is centered around the math axis and has equal height and
depth so indeed in columns that will not align horizontally
(2) there is no n|m key support in matrices so the n does nothing in
this kind of matrix

IIRC, we had added a `location=(high|middle|low)` key to change that
behaviour. (Sorry, cannot test right now).

Hi Xan,
It's not exactly what you want, but maybe it'll give you some other ideas:
\definemathmatrix[pmatrix][
left={\left(\,},
right={\,\right)},
]
\definenumber[pmatrix]
\resetnumber[pmatrix]
\define\nextmatrix{
\incrementnumber[pmatrix]
\getnumber[pmatrix].
}
\define[2]\pmatrices{
\blank[big]
\framed[frame=off]{
\startmixedcolumns[n=#1]
#2
\stopmixedcolumns
}
}
\starttext
Digueu quines de les matrius següents són regulars. Quan ho siguin,
trobeu la inversa
\pmatrices{4}{
\nextmatrix
\startpmatrix
\NC 2 \NC 3 \NR
\NC 6 \NC 7 \NR
\stoppmatrix
\column
\nextmatrix
\startpmatrix
\NC 3 \NC 2 \NC 1 \NR
\NC 4 \NC 5 \NC 3 \NR
\NC 5 \NC 0 \NC -2 \NR
\stoppmatrix
\column
\nextmatrix
\startpmatrix
\NC 5 \NC 4 \NC 2 \NR
\NC 2 \NC 2 \NC 3 \NR
\NC 7 \NC 6 \NC 5 \NR
\stoppmatrix
\column
\nextmatrix
\startpmatrix
\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
}

Another bug.
@Hans: At least for user view point it's a bug.
@Thangalin: thanks. A bigskip will solve me problems, but thanks.
