but it's not easy to be spotted...

i used 
...
\usepackage[displaymath,textmath,sections]{preview}
\begin{document}
...

but math in ams environments was not rendered in emacs

then i added a preview environment to an AMS display

\begin{preview}
  \begin{align*}
    \mat{U}\,\vet{x}_{n+1}&=\vet{z}_{n+1}\\
    \mat{L}\,\vet{z}_{n+1}&=\vet{w}_{n}
  \end{align*}
\end{preview}

i got what i wanted, yes, but i felt that going back to every AMS
environment i used was a little too much, but finally i used

...
\usepackage[displaymath,textmath,sections]{preview}
\PreviewEnvironment{align*} % etc
\begin{document}
...
and now i'm happy

now, if someone (David?) could explain a better solution or, maybe,
give the "preview whole slides" howto...

thank you,
