Hi Aditya,
Thanks for sharing this nice module, it is really useful, especially when making documents for students while using Matlab or Scilab.
Nice indeed.

There is also in the distribution the module m-matrix.mkiv written by Hans and Jeong Dalyoung, which allows to manipulate matrices.
Maybe one should add the functionality of your module to the one in the distribution and somehow unify their environments.
I'll add this to the core:

\unprotect

%D The following code is derived from Aditya's simplematrix prototype but
%D adapted to regular mathmatrices (which saves some code so it can go into
%D the core):

\newtoks\t_math_matrix

\def\math_matrix_simple_row#1%
   {\rawprocesscommalist[#1]\math_matrix_simple_col
    \toksapp\t_math_matrix{\NR}}

\def\math_matrix_simple_col#1%
   {\toksapp\t_math_matrix{\NC#1}}

\unexpanded\def\math_matrix_simple[#1][#2]#3%
   {\begingroup
    \edef\currentmathmatrix{#1}%
    \ifsecondargument
      \setupcurrentmathmatrix[#2]%
    \fi
    \t_math_matrix\emptytoks
    \processlist[];\math_matrix_simple_row[#3]%
    \math_matrix_start\currentmathmatrix
    \the\t_math_matrix
    \math_matrix_stop
    \endgroup}

%D We hook it into the normal mathmatrix code:

\ifdefined\c!simplecommand\else\def\c!simplecommand{simplecommand}\fi

\appendtoks
     \edef\p_simplecommand{\mathmatrixparameter\c!simplecommand}%
     \ifx\p_simplecommand\empty\else
 
\setuevalue{\p_simplecommand}{\dodoubleempty\math_matrix_simple[\currentmathmatrix]}%
     \fi
\to \everydefinemathmatrix

%D And predefine some matrices:

\definemathmatrix[matrix:parentheses][\c!left={\left(\mskip\thinmuskip},\c!right={\mskip\thinmuskip\right)},\c!align=\v!middle]
\definemathmatrix[matrix:brackets] 
[\c!left={\left[\mskip\thinmuskip},\c!right={\mskip\thinmuskip\right]},\c!align=\v!middle]
\definemathmatrix[matrix:bars] 
[\c!left={\left|\mskip\thinmuskip},\c!right={\mskip\thinmuskip\right|},\c!align=\v!middle]

\definemathmatrix[thematrix][matrix:parentheses][\c!simplecommand=thematrix]

\protect

\starttext

$\thematrix{1,2,3,4;5,6,7,8;9,10,11,12}$

$\startthematrix
     \NC 1\NC 2\NC 3\NC 4\NR
     \NC 5\NC 6\NC 7\NC 8\NR
     \NC 9\NC10\NC11\NC12\NR
\stopthematrix$

\stoptext
...
Best regards: OK

If you type a lot of such matrices, you might find the attached module interesting. Using it you can use matlab-like syntax for writing matrices:
\usemodule[simplematrix]
\definesimplematrix[MATRIX][fence=parenthesis, align=middle]
\starttext
$\MATRIX{1,2,3,4;5,6,7,8;9,10,11,12}$
\stoptext
