Problem with \definemathmatrix

Problem with \definemathmatrix

[-- Attachment #1.1: Type: text/plain, Size: 761 bytes --]

Hello,
This macro that is not mine worked very well. I just tested the following
file and there is a problem.
Thank you
Fabrice

\definemathmatrix
  [pmatrix]
  [left={\left(\,},right={\,\right)}]

\starttext

\math{M^3=\startpmatrix
       \NC 2 \NC 3 \NC 6  \NC 4 \NC 2 \NC 7  \NC 3  \NC 1 \NR
       \NC 3 \NC 0 \NC 1  \NC 1 \NC 2 \NC 3  \NC 6  \NC 4 \NR
       \NC 6 \NC 1 \NC 4  \NC 4 \NC 4 \NC 9  \NC 10 \NC 6 \NR
       \NC 4 \NC 1 \NC 4  \NC 4 \NC 5 \NC 8  \NC 8  \NC 3 \NR

Hi Fabrice,

I think the problem comes from a blank line in your matrix (after your last line of entries in your matrix). The following works fine for me:

\definemathmatrix
  [pmatrix]
  [left={\left(\,},right={\,\right)}]
  
\starttext

\startformula
A = \startpmatrix
\NC 11 \NC 12 \NR
\NC 21 \NC 22 \NR
\stoppmatrix
\stopformula

\startformula
M^3 = \startpmatrix
       \NC 2 \NC 3 \NC 6  \NC 4 \NC 2 \NC 7  \NC 3  \NC 1 \NR 
       \NC 3 \NC 0 \NC 1  \NC 1 \NC 2 \NC 3  \NC 6  \NC 4 \NR  
       \NC 6 \NC 1 \NC 4  \NC 4 \NC 4 \NC 9  \NC 10 \NC 6 \NR  
       \NC 4 \NC 1 \NC 4  \NC 4 \NC 5 \NC 8  \NC 8  \NC 3 \NR  
       \NC 2 \NC 2 \NC 4  \NC 5 \NC 2 \NC 7  \NC 3  \NC 1 \NR  
       \NC 7 \NC 3 \NC 9  \NC 8 \NC 7 \NC 8  \NC 10 \NC 3 \NR  
       \NC 3 \NC 6 \NC 10 \NC 8 \NC 3 \NC 10 \NC 4  \NC 1 \NR  
       \NC 1 \NC 4 \NC 6  \NC 3 \NC 1 \NC 3  \NC 1  \NC 0 \NR  
\stoppmatrix
\stopformula

\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

Hello,
Thank you.
@Adytan This module is not part of context standalone, in which directory
is it better to put it ?

You can put it any directory where ConTeXt can find it. I usually use

$TEXMFHOME/tex/context/personal/

On most systems, $TEXMFHOME is set to ~/texmf.

Re: Problem with \definemathmatrix

[Otared Kavian]

Hi Aditya,

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

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.

Best regards: OK

Nice indeed.

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
