[NTG-context] hairline in a matrix

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 }
