math-ams.tex: \triangleup?

math-ams.tex: \triangleup?

[Christopher Creutzig]

Dear Hans,

  math-ams.tex defines \triangledown, but for symmetry it should
imhoalso define \triangleup:

\definemathsymbol [triangleup]        [ord]   [ma] ["4D]

The symbol is currently only defined as \vartriangle, but that is a
relation.

regards,
	Christopher Creutzig

ok, done, but it's the sams as vartriangle (i suppose that math guru's know the difference in usage -)

  The spacing around it is different, ord vs. rel.  Those who don't see 
the difference may not deserve it. :-)

Math Diagrams in ConTeXt

[Matthias Weber]

Hello all,

I  need to typeset a few (simple) diagrams in ConTeXt,
like the ones mathematicians use, with arrows. In LaTeX, one can use
pictex or DCpic. The latter claims also to work with ConTeXt, but I 
couldn't find
an example. Has anybody managed to do something like this? 
(essentially, I only need something like



      Math Text  ---------->  Math Text  ---------->  Math Text
           |                                      |                      
              |
           |                                      |                      
              |
           |                                      |                      
              |
           v                                     v                       
            v
      Math Text  ---------->  Math Text  ---------->  Math Text

sometimes also with diagonal arrows).

Thanks

Without diagonal arrows you could use the flow charts module.

Thanks -- while it looks really nice, I do need diagonal arrows.

However, after some experimenting, I catually managed to get DCpic to 
work. It is just a plain TeX file,
I was only scared by the .sty name.

If somebody else runs into the same problem, here is a short example, 
for reference. You will need dcpic.sty in  your path first. Then
one can create diagrams as follows:

\usemodule[pictexwd]
\input dcpic.sty

\starttext

\begindc{\commdiag}
\obj(1,2){$V_i$}
\obj(3,1){$V'$}
\obj(3,3){$V$}
\mor{$V_i$}{$V$}{$f_i$}
\mor{$V_i$}{$V'$}{$f_i'$}[-1,0]
\mor{$V$}{$V'$}{$f$}
\enddc


\stoptext

Why not use MetaPost?  With all of ConTeXt's features for doing in-document 
MetaPost code, this would be the perfect solution for your problem.  Have a 
look at Hans's MetaFUN manual for a good starting point on using it.

Also, I believe the original MetaPost manual has some examples of figures 
very much like the ones that you want to draw.

Hi,

although you already have solved your problem, I encourage you to have a
look at the metaobj package for metapost. The 'PSTricks/METAOBJ gallery'
part of the manual (p. 93ff) shows some diagrams you will surely like.

Greetings,
