Updated My Way on math alignment

Updated My Way on math alignment

[Aditya Mahajan]

Hi,
  I have updated myway on using alignment. It now also explains 
features of matrix (similar to array of latex), cases, substack and 
intertext. Most of the discussion on mathalignment (similar to align 
and gather environments of latex) is the same as before.

Taco, I am also describing how to use style=... feature of matrix that 
you sent a while back, hoping that it will make to the core :-)

I have a question about \startcases .. \stopcases.
I am trying to adjust the distance of the cases and the right brace, the 
left brace is empty,
see example below. Is this possible ?
Kind regards
Wim

% Example
\starttext
\startformula
*\startcases[left={\left.},right={\right\}}]*
\NC (\lambda + \mu ) \cdot a = \lambda \cdot a + \mu \cdot a \NC \NR
\NC \lambda ( a + b ) = \lambda \cdot a + \lambda \cdot b  \NC \NR
\stopcases
\text{(distributieve eigenschappen)}
\stopformula
\stoptext

It is. You can do it in different ways, depending on what you like.

  \starttext

The original one.

  \startformula
  \startcases[left={\left.},right={\right\}}]
  \NC (\lambda + \mu ) \cdot a = \lambda \cdot a + \mu \cdot a \NC \NR
  \NC \lambda ( a + b ) = \lambda \cdot a + \lambda \cdot b  \NC \NR
  \stopcases
  \text{(distributieve eigenschappen)}
  \stopformula

You can reduce the \quotation{width} of the cases,

\startformula
\startcases[left={\left.},right={\right\}},numberdistance=0pt]
  \NC (\lambda + \mu ) \cdot a = \lambda \cdot a + \mu \cdot a \NC \NR
  \NC \lambda ( a + b ) = \lambda \cdot a + \lambda \cdot b  \NC \NR
  \stopcases
  \text{(distributieve eigenschappen)}
  \stopformula

or use a matrix (only one column)

\startformula
   \startmatrix[left={\left.},right={\right\}}]
     \NC (\lambda + \mu ) \cdot a = \lambda \cdot a + \mu \cdot a \NR
     \NC \lambda ( a + b ) = \lambda \cdot a + \lambda \cdot b    \NR
  \stopmatrix
  \text{(distributieve eigenschappen)}
  \stopformula

maybe a right aligned one

\startformula
   \startmatrix[left={\left.},right={\right\}},align=right]
     \NC (\lambda + \mu ) \cdot a = \lambda \cdot a + \mu \cdot a \NR
     \NC \lambda ( a + b ) = \lambda \cdot a + \lambda \cdot b    \NR
  \stopmatrix
  \text{(distributieve eigenschappen)}
  \stopformula

  and this is how I would do it

\definemathmatrix[aligned][n=2,align={right,left},distance=0pt]

\startformula
   \startaligned[left={\left.},right={\right\}}]
     \NC (\lambda + \mu ) \cdot a \NC{} = \lambda \cdot a + \mu \cdot a 
\NR
     \NC \lambda ( a + b ) \NC {}= \lambda \cdot a + \lambda \cdot b 
\NR
\stopaligned
  \text{(distributieve eigenschappen)}
  \stopformula

I did not know the numberdistance existed, I would think it specifies the
distance between the columns and the number of the equation. Anyways 
your solutions work like a charm.

Many thanks for your help.
