You can right align all columns, though I am not sure that this looks better, 
because column 2 and 3 now appear to be "too close".

\definemathmatrix[bmatrix]
  [matrix:brackets]
  [align=all:right,simplecommand=bmatrix]
\starttext
$ a \rightarrow
  \bmatrix{1, 2, 3, 4;
   2, 1, 4, 3;
   3,-4, 1,-2;
   4,-3, 2,-1} $
\stoptext

See if this way suits you.
\definemathmatrix[bmatrix]
  [matrix:brackets]
  [simplecommand=bmatrix]
\starttext
$ a \rightarrow
  \bmatrix{1, \hfill 2, 3, \hfill 4;
   2, \hfill 1, 4, \hfill 3;
   3,-4, 1,-2;
   4,-3, 2,-1} $
\stoptext

[NTG-context] Aaligned numbers in a matrix?

[Bruce Horrocks via ntg-context]

I'm using the following MWE to produce a matrix:

\definemathmatrix[bmatrix]
  [matrix:brackets]
  [simplecommand=bmatrix]
\starttext
$ a \rightarrow
  \bmatrix{1, 2, 3, 4; 
   2, 1, 4, 3;
   3,-4, 1,-2;
   4,-3, 2,-1} $
\stoptext

The columns with negative numbers in are centred and I would rather have them 
right-aligned so that the digits stack up above each other and the negative 
signs stick out to the left, so to speak. Is there an easy way to achieve this?
