Hello,
I'm looking vor a way to unterline one line of a matrix.
I use the matrix for an equation and the last line should be

\underline works only for the single entries but not for the whole

This macro gives both a vertical line and a horizontal for an entire  
matrix.  It's crude, but it works.  You should be able to do something  
similar.  It may require ERT, I haven't tried setting up array  
formatting in LyX yet.


\newcommand{\system}[4]{ \mbox{$\displaystyle \left[
\begin{array}{c|c} {#1}  {#2} \\ \hline {#3}  {#4} \\
\end{array} \right]$} }
