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 ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : https://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________
