Thank you. Of course most of the work has actually been done by
others so far, and my only job has been that of bringing things
together :)

Yes, it's still in my TODO list. Sadly, I don't have enough
time to work on it these days :\
What you've done so far is already a great piece of work. :) Without

Yes, it's still in my TODO list. Sadly, I don't have enough
time to work on it these days :\

You want to use the nath module: all equations are multiline:

You want to use the nath module: all equations are multiline:

\[ a= b + \\
   c + d + \\
   e +
\]

You may want to look at the documentation for the nath package
in LaTeX about the use of \wall and \return for alignments
within multiline equations.

Yup, I just changed a couple of things and now we have a
\startbigcases ... \stopbigcases for this. Will upload new
version soon.
Oh, great! I'm really looking forward to get this new version. By the  
way, would you be so kind to include some multiline equation  
environment? Something like (or better than)

\[
 first part of very long equation
 \eqbreak
 second part of very long equation
 \eqbreak
 third part of very long equation
\]
which I achieve at the moment by doing
\[
 \startalign
   first part of very long equation
   \hskip 1.5em
   \\ \hfill
   second part of very long equation
   \\ \hfill
   third and part of very long equation
 \stopalign
\]
But this does not work as well I wish. I'd like to substitute the  
'\hskip 1.5 em' after the first line for a '\hfill' so that it always  
be the leftmost line, but the latter does nothing at all. So I have to  
put a '\hskip' and tweak the distance by hand.

Thanks for you help,
David

Hello David, sorry for the delay.

The problem is caused by \frac being defined in the newmat
module as

%D Better:

\def\frac#1#2{\mathematics{\genfrac{}{}{}\donothing{#1}{#2}}}


If you comment that line, it will compile flawlessly.

Hans, why would you want to allow \frac in text mode?

(Yes.)

Yup, I just changed a couple of things and now we have a
\startbigcases ... \stopbigcases for this. Will upload new
version soon.

[NTG-context] amsl: startcases/stopcases

2004-05-20 Thread David Munger
Hello Giuseppe,
I'm having a little trouble with the cases in amsl.
Compiling this:
\[
 f(x) =
 \startcases
   0& \text{if $x < -\epsilon$} \\
   \frac12  & \text{if $x >  \epsilon$}
 \stopcases
\]
results in an error around the \frac. Changing it to \dfrac makes the  
input compile ok, but typesets the cases in an ugly manner with really  
narrow spacing.

Is there some way of telling startcases/stopcases to behave in display  
mode?

Thanks in advance,
David
