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
