formla: listing and subnumbering

formla: listing and subnumbering

[Peter Schorsch]

Hi,

in my work I have a lot of formulas inkl. subformulas. Doing the examples at 
the wiki two questions came up:
 a) how to generate a table of formulas?
 b) what is the right/better way for subnumbering?

a) I tried the example for generating a table of formulas from the wiki
(http://wiki.contextgarden.net/Math/Display#List_of_Formulas) but instead of 
a list I get in the pdf a »no list method«. What do I missed here?

b) I found two descriped ways how to create formula (sub-)numbering:
     1) using \formulanumber and \subformulanumber (third example from 
http://wiki.contextgarden.net/Math/Display#The_Manual_Method). But context 
always reports here: ! Undefined control sequence.
<argument> ...^{\vfrac {1}{2}} &\subformulanumber 
                                                  {b}\cr a^2 + b^2 &= c^2 
&\...
      2) using the \NR[..] like it is described on 
http://wiki.contextgarden.net/Multiline_equations#Working_with_equation_numbering 
and http://dl.contextgarden.net/myway/mathalign.pdf. This way compiles 
through. 

But which way is the future context way? In which way can I combine 
subnumbering and including to list some (not all) subformulas?

Thanks for your help

Did you found anything?

I tried to figure out which command in the examples of the wiki work/dont 
work (I used mkiv stable). So far:

\formulanumber -> works in mkii and mkiv
\subformulanumber -> works only in mkii
\placenamedsubformula -> works only in mkii
\placesubformula & \NR[+] -> mkii & mkiv, but (1.name) as number
\placeformula & \NR[+] -> works in mkii and mkiv, but (1.name) as number

I have a real problem to transform my formula from mkii to mkiv. In mkii I 
had following:

\placesubformulawithnumber[gleichung1]
\startformula
\startalign[n=3, align={right,middle,left}]
\NC PM \xrightarrow{aaa} \NC R_{PM} \NC \xrightarrow{bbb} PM 
\NR[gleichung1a][.1]
\NC R_{PM} \NC = \NC \{ K, F \} \NR[gleichung1b][.2]
\stopalign
\stopformula

Can anyone help me to transform this to mkiv, please?

Thanks
P.

- can you post your examples (so that they can be added to the test suite)

- can you also test this with the current beta

done.. you can find the test file for formulas with mkiv attached to this 
email. 

I ran it with the latest beta. A couple of things are working.. but e.g. 
most ways for subformulas not.

The listing is half working.. only the formulas names are missing and the 
order with the only example with working subformulas is strange. 

If I made any mkiv mistake please excuse... I tried to figure out / guessed 
the right mkiv ways. 

I hope this test files helps you to identify the problem areas.

\starttext
\title{List of formulas}

Strange: Missing name of first formula and strange order of .. 2.a, 2,

\placelist[formula][criterium=all,alternative=c]

\subject{math - formula}

This works fine.

\placenamedformula[one]{Der einfache Test}
\startformula
c^2 = a^2 + b^2.
\stopformula

\subject{math - subformula}

This works fine.

\stopformula

\placeformula[eq:second]
\startformula

\subject{math - align - formula}

Works.

\placeformula
\startformula
\startalign[n=3, align={right,middle,left}]
\NC PM \xrightarrow \NC R_{PM} \NC \xrightarrow PM \NR[gleichung1a]
\NC R_{PM} \NC = \NC \{ A, B, C, D, E\} \NR[gleichung1b]

Also works.

\placeformula
\startformula
\startalign[n=3, align={right,middle,left}]
\NC PM \xrightarrow \NC R_{PM} \NC \xrightarrow PM \NR[+]
\NC R_{PM} \NC = \NC \{ A, B, C, D, E\} \NR[+]

Does not work: no subformula numbers

\subject{math - eqalignno - formula}

Taken from wiki and removed the subformulanumber

\placeformula
\startformula
\eqalignno{
  c^2 &= a^2 + b^2  &\formulanumber \cr
  c &= \left(a^2 + b^2\right)^{\vfrac{1}{2}} &\formulanumber\cr
  a^2 + b^2 &= c^2  &\formulanumber \cr
  d^2 &= e^2        &\formulanumber \cr}
\stopformula

\subject{math - eqalignno - subformula}

Directly taken form wiki - does not work: subformulanumber is unknown.

%\placeformula
%\startformula
%\eqalignno{
%  c^2 &= a^2 + b^2  &\formulanumber{a} \cr
%  c &= \left(a^2 + b^2\right)^{\vfrac{1}{2}} &\subformulanumber{b}\cr
%  a^2 + b^2 &= c^2  &\subformulanumber{c} \cr
%  d^2 &= e^2        &\formulanumber\cr}
