It looks pretty much like the AMS-LaTeX variation. Below is another example of use, as a displayed formula. ---- % Defines a small two-by-two matrix. \def\twomatrix#1#2#3#4{\startsmallmatrix\NC{#1}\NC{#2}\NR\NC{#3}\NC{#4}\NR\stopsmallmatrix} % The Pauli spin matrices, explicit forms. \def\pspint{{\twomatrix1001}} \def\pspinx{{\twomatrix0110}} \def\pspiny{{\twomatrix0{-𝕚}𝕚0}} \def\pspinz{{\twomatrix100{-1}}} Pauli spin matrices \startformula σ^0 ≔ \pspint, \quad σ^3 ≔ \pspinz, \quad σ^1 ≔ \pspinx, \quad σ^2 ≔ \pspiny \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 : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________
