Dear Weber Mattias,

Please see page 10 of “mathalign.pdf” made by Aditya.
He showed the way of writing  aligned math including  matrices.
For example,

\startformula

 \startmatrix[left={\left(\,},right={\,\right)}]

      \NC 1 \NC 0 \NC 0 \NR
      \NC 0 \NC 1 \NC 0 \NR
      \NC 0 \NC 0 \NC 1 \NR
    \stopmatrix 
  \stopformula 
There are many other examples that you can use.

Best regards,
Dalyoung

Re: Vertical lines in matrices

[Weber, Matthias]

Thanks Jeong,

I was aware of this. While there is no solution that adds vertical lines into matrices, one can juxtapose two (or more) of them with
properly chosen delimiters, like so:

\definemathmatrix
  [bvmatrix]
  [left={\left(\,},right={\ \right\vert}]

\definemathmatrix
  [rbmatrix]
  [left={\left.\,},right={\,\right)}]
  
\starttext
\startformula
\startbvmatrix
\NC 0 \NC  0\NC  0 \NR
\NC 1 \NC  0\NC  1 \NR
\stopbvmatrix
\startrbmatrix
\NC  0 \NR
\NC  1 \NR
\stoprbmatrix
\stopformula
\stoptext

It should not be too difficult to support "proper" vertical and horizontal lines. It should be possible to just add solid lines relatively easily. With dashed and other forms of lines, it is more a question of finding the right user-interface than anything else.

Can you give more details of the features and visual output that you are looking for?

Aditya

Re: Vertical lines in matrices

[Weber, Matthias]

Hi Aditya,

Ideally I would like to be able to typeset blocks in block matrices visually separated, as for instance is done in

https://tex.stackexchange.com/questions/23853/specific-blockmatrices/23857

My current solution for just vertical lines below has the drawback that it uses the standard delimiter \vert for the vertical line(s),
which is too thick for my taste.

Thanks,

Matthias

  [bvmatrix]
  [left={\left(\,},right={\ \right|}]

\definemathmatrix
  [rbmatrix]

\startformula
\startbvmatrix

Vertical lines in matrices

[Weber, Matthias]

Dear List,

I am trying to get vertical (separating) lines into matrices, as is possible in tables:

\starttext
\startformula
\left(
\starttable[|c|c|c|]
\NC 0 \NC  0\VL  0 \FR
\NC 1 \NC  0\VL  1 \FR
\stoptable
\right)
\stopformula
\stoptext

But my parentheses don’t fit, and I am not sure whether using tables in math mode is the proper way of doing things.
\startmatrix seems to ignore a \VL.

Any. suggestions?

Thanks,

Matthias
