Hi, I cannot understand why, but multiline formulas are not numbered.
\starttext % has number \placeformula \startformula f(x_0, u_0)=0. \stopformula % has no number \placeformula \startformula \startalign \NC \dot{x}(t) \NC=f(x(t), u(t)) \NR \NC y(t) \NC=h(x(t), u(t)), \NR \stopalign \stopformula % no numbers even here \startsubformulas \placeformula \startformula \dot{x}(t)=f(x(t), u(t)) \stopformula \placeformula \startformula y(t) =h(x(t), u(t)), \stopformula \stopsubformulas \stoptext Regards, Vyatcheslav ___________________________________________________________________________________ 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 : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________
