hairline in a matrix

hairline in a matrix

[Peter Schorsch]

Hi,

I could not figure out how to add a hairline between two rows of a matrix. 

Following example is compiling but only results in a bigger vertical space.
Infos/Hints are welcome...


\startformula \startmatrix
   \NC {a_1 } \NC {a_2 } \NC {a_3 }  \NC  \ldots      \NC {a_X }  \NR
   \NC {b_1 } \NC 0      \NC 0       \NC 0            \NC 0       \NR
   \NC 0      \NC {b_2 } \NC 0       \NC 0            \NC 0       \NR
   \NC 0      \NC 0      \NC  \ddots \NC 0            \NC 0       \NR
   \NC[n=5] {\text{\hairline}} \NR
   \NC 0      \NC 0      \NC 0       \NC {b_{X - 1} } \NC 0       \NR
\stopmatrix \stopformula
