Dear Idris,

I have used buffers and \plcadefigures to display formula and figure together. Here is my short sample file.

\startbuffer[one] \startformula \startmatrix \NC \NC e_1 \NC e_2 \NC e_3 \NC e_5 \NC e_5 \NR \NC u \NC 0 \NC 1 \NC 1 \NC 0 \NC 1 \NR \NC v \NC 1 \NC 0 \NC 1 \NC 0 \NC 0 \NR \NC w \NC 1 \NC 1 \NC 0 \NC 1 \NC 0 \NR \NC x \NC 0 \NC 0 \NC 1 \NC 0 \NC 1 \NR \NC y \NC 1 \NC 0 \NC 0 \NC 1 \NC 0 \NR \stopmatrix \stopformula \stopbuffer

\starttext

\placefigure[here][fig:test]{Test of buffers} {\startcombination[2*2] {\externalfigure[7starmagic1][width=.25\makeupwidth]}{G} {\externalfigure[one.tmp]}{AA} {\externalfigure[one.tmp]}{BB} {\externalfigure[one.tmp]}{CC} \stopcombination}

\stoptext

Then, I got a strange output(fig 1: wide blank spaces between columns). If I use \getbuffer instead of \externalfigure, I got somewhat proper output(fig 2), but the figure is located much higher than the matrix(horizontal alignment is bad).

What is wrong in my sample? Is there any option for \startcombination?

\start-stopformula are for math display mode ($$-$$). Apparently having display mode turned on within the buffer creates the extra space. Since you are using combinations for your display there is no need for display mode. The following works here:

=============== \startbuffer[one] %\startformula

\startmatrix \NC \NC e_1 \NC e_2 \NC e_3 \NC e_5 \NC e_5 \NR \NC u \NC 0 \NC 1 \NC 1 \NC 0 \NC 1 \NR \NC v \NC 1 \NC 0 \NC 1 \NC 0 \NC 0 \NR \NC w \NC 1 \NC 1 \NC 0 \NC 1 \NC 0 \NR \NC x \NC 0 \NC 0 \NC 1 \NC 0 \NC 1 \NR \NC y \NC 1 \NC 0 \NC 0 \NC 1 \NC 0 \NR \stopmatrix %\stopformula \stopbuffer

\starttext

\setupcombinations[distance=2cm]

\placefigure[here][fig:test]{Test of buffers} {\startcombination[2*2] % {\externalfigure[7starmagic1][width=.25\makeupwidth]}{G} {\externalfigure[one.tmp]}{AA} {\externalfigure[one.tmp]}{BB} {\externalfigure[one.tmp]}{CC} {\externalfigure[one.tmp]}{DD} \stopcombination}

\stoptext

I would also add $\displaystyle ... $ around the matrices. Aditya
