eqalign

eqalign

[nohop]

Dear All,

The command \eqalign does not work as described under:
   https://wiki.contextgarden.net/Math_with_newmat
as the ampersands are typeset (and the equal signs unaligned).

The following minimal example shows the issue:
-------------
\usemodule[newmat]

\starttext

\startformula
\eqalign{
      A & = x\cr
        & = y\cr}
\stopformula

\stoptext
-------------

(Issue showing up in context 2019.11.14 17:07.)

Best regards.

Hi,

Indeed in ConTeXt one has better to use \startalign. Please see the excellent explanations by Aditya

OK, thanks for the tip! It works indeed.

PS: There appears to be no mention of \startalign in the manual. Is this going to be a stable interface? \eqalign, \eject used to work in ConTeXt.

Re: eqalign

[Otared Kavian]

Hi,

Indeed \startalign has been there from the beginning (as far as I can remember) and it is stable. 
In fact, as expalined by Aditya, you can define your own align environment, for special purposes. for instance I have:

\definemathmatrix[alignedcases]
		[align={right,left,left},
		distance=3pt,
		left={\left\{},
		right={\right.},
		style=\displaystyle]

when I want to put a big brace to the left of a certain number of aligned equations.

Best regards: Otared K.

Which manual?

Probably: http://dl.contextgarden.net/myway/mathalign.pdf

1. \eqalign still works but you have to change the meaning of the 
ampersand in math mode but I suggest to use \startalign.

\setupmathematics[ampersand=normal]

\starttext

\startformula
\eqalign{
      A & = x\cr
        & = y\cr}
\stopformula

\stoptext

2. There is no need for \eject because we have the \page command.

Wolfgang

This will work. I have also tons of \eqalign groups, some of them  
nested, and all
seems fine now.

Taco, Hans, et al,

I'm hesitant to upgrade as I have several hundred eqalign groups in  
my work. Can you tell me if this now works in the new version?

%output=pdf
\starttext
\placeformula[-]
\startformula
    \eqalign{
      f(x)&=x^2-2x-3\cr
      f(x)&=(x-3)(x+1)}
\stopformula
\stoptext
