mathmatrix and internal lines

mathmatrix and internal lines

[Jean-Philippe Rey]

[-- Attachment #1: Type: text/plain, Size: 944 bytes --]

Dear list,

I would like to draw matrices with internal lines as can be done with LaTeX (cf pdf output) :

========================
\documentclass{article}
\begin{document}
$M =\left( \begin{array}{c|c}
A & B \\
\hline
C & D \\
\end{array} \right)$
\end{document}
========================

I didn't find out how to use mathmatrix to achieve this. My best result to date is 

========================
\starttext
$M = \left( \bTABLE[frame=off]
\bTR
	\bTD[rightframe=on, bottomframe=on] $A$ \eTD
	\bTD[bottomframe=on] $B$ \eTD
\eTR\bTR
	\bTD[rightframe=on] $C$ \eTD
	\bTD $D$ \eTD
\eTR
\eTABLE \right)$
\stoptext
========================

The code is rather ugly, and I get a spurious space at the bottom of the table.

Any hints?

Thank you,

Re: mathmatrix and internal lines

[Otared Kavian]

Hi Jean-Philippe,

For a simple case like the one you sent, a rather not optimal solution can be this:

\definemathmatrix[mymatrix]
	[left={\left(\,},
	right={\ \right)}]
	
\starttext
\startformula
	\startmymatrix
		\NC A \hskip .5em |\hskip-.5em  \NC B \NR
		\noalign{\hrule}
		\NC C \hskip .5em |\hskip-.5em \NC D \NR
	\stopmymatrix
\stopformula
\stoptext

However I think I have seen sometime ago a more elegant solution, but I could not find it right now…

Best regards: Otared K.

Re: mathmatrix and internal lines

[Otared Kavian]

Hi Jean-Philippe,

The following is better than the one I sent earlier:

\definemathmatrix[mymatrix]
	[left={\left(\,},
	right={\ \right)}]
	
\starttext
\startformula
	\startmymatrix
		\NC A \NC\hskip-.5em \vrule  \NC\hskip-.5em B \NR
		\noalign{\hrule}
		\NC C \NC \hskip-.5em\vrule \NC \hskip-.5em D \NR
	\stopmymatrix
\stopformula
\stoptext

Best regards: Otared K.

Re: mathmatrix and internal lines

[Jean-Philippe Rey]

[-- Attachment #1.1: Type: text/plain, Size: 3358 bytes --]

Hi Otared,

Thank you very much.

I used your example to write the following macros. They are far from perfect but suit my needs.  A few days ago, Hans warned not to use \noalign in LMTX, so I used the trick he gave to the list even if I don't really understand it.

=== LMTX version ============
%D \macros{HR, VR}
%D \type{\HR} draws a horizontal rule between two rows of a matrix
%D \type{\VR} is used in place of \type{\NC} to draw a vertical rule between two columns of a matrix
%D each macro takes an optional parameter giving the rule dimensions
%D Example
%D  \type{\startmatrix \NC A \VR[depth 2mm] B \NR \HR[height 0.6pt] \NC C \VR D \NR \stopmatrix}
 
\pushoverloadmode
\noaligned\tolerant\protected\def\HR[#1]{\noalign{\hrule #1}}
\popoverloadmode

\def\VR{\dosingleempty\doVR}
\def\doVR[#1]{\NC \hskip-0.5em \vrule #1 \hskip-0.5em \NC}
===========================

=== MkIV version ============
%D \macros{HR, VR}
%D \type{\HR} draws a horizontal rule between two rows of a matrix
%D \type{\VR} is used in place of \type{\NC} to draw a vertical rule between two columns of a matrix
%D it takes an optional parameter giving the rule dimensions
%D Example
%D  \type{\startmatrix \NC A \VR[depth 2mm] B \NR \HR \NC C \VR D \NR \stopmatrix}
 
\def\HR{\noalign{\hrule}}

\def\VR{\dosingleempty\doVR}
\def\doVR[#1]{\NC \hskip-0.5em \vrule #1 \hskip-0.5em \NC}
===========================

For the MkIV version I haven't been able to add an optional parameter to \HR the code

\def\HR{\dosingleempty\doHR}
\def\doHR[#1]{\noalign{\hrule #1}}

complains about "Misplaced \noalign"

Best regards,

Re: mathmatrix and internal lines

[Otared Kavian]

Hi Jean-Philippe,

A few weeks ago I saw briefly the discussion about Hans' message regarding \noalign and the the new definitions of \HR and \VR that you are sending. Indeed your solution works great !
Just for the case other people may have the same question about writing block matrix, I copy below the whole example which can be found later in the mail archive.
(For mkiv, I don't know how to do the same thing…).

%%% begin block-matrix.tex
% in LMTX defining \HR and \VR to create block matrices:
\pushoverloadmode
\noaligned\tolerant\protected\def\HR[#1]{\noalign{\hrule #1}}
\popoverloadmode

\def\VR{\dosingleempty\doVR}
\def\doVR[#1]{\NC \hskip-0.5em \vrule #1 \hskip-0.5em \NC}

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

\starttext	

\startformula
	\startmymatrix
		\NC A \VR  B \NR
		\HR
		\NC C \VR  D \NR
	\stopmymatrix
\stopformula

\stoptext
%%% end block-matrix.tex

Best regards: Otared K.

The \noaligned permits a \protected definition. Otherwise one has to do 
something

\def\VR{\noalign\bgroup
   <command that picks up [#1]

that command then does the rule and ends the noalign. Also, that one 
cannot be \protected (a pitty in case one uses \expanded or so)

So ... a multistep approach. Plenty of that in mkiv.

given the \HR definition that should be

\tolerant\protected\def\VR[#1]{\NC ...\NC}

Anyway, a feature like this should be in sync with other table 
mechanisms, so

\definemathmatrix
   [mymatrix]
   [left={\left\lparent\thinspace},
    right={\thinspace\right\rparent}]

\starttext

\startformula
	\startmymatrix
		\NC A \VL  B \NR
		\HL
		\NC C \VL  D \NR
	\stopmymatrix
\stopformula

\startformula
	\startmymatrix
		\NC A \VL[3,green]  B \NR
		\HL[10,red]
		\NC C \VL  D \NR
	\stopmymatrix
\stopformula

\stoptext

A bit more code needed but the next upload will have it. Of course you 
have to wikify it.

Hi Hans,

Thanks for your insight!
Indeed I'll wikify what you explained, once I have tested it with the next upload. Would  \HL and \VL be also available in mkiv ?

Best regards: Otared

Dunno yet ... it's not that hard but I'm in lmtx mode now.

Hi,
I created a page on the wiki:
	https://wiki.contextgarden.net/Matrix_in_maths <https://wiki.contextgarden.net/Matrix_in_maths>
However the LMTX code is not typeset on the wiki. I'll see with taco whether it is possible to have lmtx mode on the wiki.

Best regards: Otared K.

I added some details and examples to the wiki, however, as you said, they are not typeset correctly.

Great! Well done. 
I'll ask Taco about LMTX on the wiki.

I plan to update the lmtx on the wiki sometime between now and new years’ eve. 
Sorry, I can not be more precise right now.

Best wishes,
Taco
