Re: How to draw a red frame of a row in a matrix?

[Otared Kavian <otared@gmail.com>]

Hi Dalyoung,

Is this what you want:

\setupcolors[state=start]
\def\RedMath{\mframed[frame=on,
	framecolor=red,
	offset=2pt,
%	background=color,
%	backgroundcolor=lightred,
%	backgroundoffset=2pt
	]}

\starttext
\startformula
\startmatrix[left={\left (\,},right={\,\right)}]
\NC\startmatrix[left=,right=,]
\NC a_{11} \NC a_{12} \NC \dots \NC a_{1n} \NR
\NC \vdots \NC \vdots \NC \vdots \NC \vdots \NR
\stopmatrix\NR
\NC\RedMath{\startmatrix[left=,right=,]
\NC	 a_{i1} \NC a_{i2} \NC \cdots \NC a_{in} \NR
\stopmatrix}\NR
\NC\startmatrix[left=,right=,]
\NC \vdots \NC \vdots \NC \ddots \NC \vdots \NR
\NC	 a_{m1} \NC a_{m2} \NC \cdots \NC a_{mn} \NR
\stopmatrix\NR
\stopmatrix
\stopformula 
\stoptext


Best regards: OK
