I found that late2thml has problems with mirror in eqnarray environment.
It can be due to the fact, that eqnarray and matrix has the same row
separator - . The first is treated as from eqnarray and the rest of
matrix is treated as another part of eqnaray. From this point all the
equation are renumbered and displayed in unproper place and order.
Are you using \usepackage{amsmath} ?
no,
Please provide example coding which does not work for you.
The example latex file is very simple:
\documentclass[12pt]{article}
\usepackage[polish]{babel}
\usepackage{t1enc}
\usepackage[latin2]{inputenc}
\usepackage[dvips]{graphicx}
\begin{document}
\selectlanguage{polish}
\begin{eqnarray}
\sigma_x=\left( \matrix{01\cr 10}\right),
\sigma_y=\left(\matrix{0-i\cr i0}\right),
\sigma_z=\left(\matrix{10\cr 0-1}\right).
\end{eqnarray}
Ahah, you are mixing plain TeX syntax with LaTeX.
This ought to be:
\begin{eqnarray}
\sigma_x=\left( \begin{matrix}01\\ 10\end{matrix}\right)\,,\quad
\sigma_y=\left(\begin{matrix}0-i\\ i0\end{matrix}\right)\,,\quad
\sigma_z=\left(\begin{matrix}10\\ 0-1\end{matrix}\right)\,.
\end{eqnarray}
(See the result (with amsmath loaded) at:
http://www-texdev.ics.mq.edu.au/MIREK/eqntest/
)
so that LaTeX2HTML can detect the sub-environments,
and treat those separately, before parsing the {eqnarray}
But if you are using advanced mathematical structures, such
as matrices and aligned sets of equations, then you really
should be using \usepackage{amsmath}.
This allows advanced structures to be specified in a more
intuitive manner --- rather than just trying to draw pieces
on a page, expecting the resulting visual effect to carry
the intended meaning.
In LaTeX2HTML, the results for mathematics are generally
much better when {amsmath} is loaded, than when not loaded,
because the various types of alignments give a better clue
as to what kind of layout structure should be used in the HTML,
and that images are more likely to be appropriate.
\end{document}
latex2html treats it strangely, first it knows there is only one
formula, and on the other hands it tries to split the eqnarray into
several (here 3 ??) formulae.
An {eqnarray} is designed to create 3 columns in LaTeX.
You may not always choose to use all the columns, but
LaTeX2HTML will nevertheless construct a TABLE with 3 cols.
because that's the purpose of an {eqnarray}.
You have the choice of using {equation} of {displaymath}
environments, if you want a single column, with/out numbering.
If you ad some more formulae to this document you will see what will
happen. Everything gets mixed.
and the version of latex2html:
$ latex2html --version
[english]This is jLaTeX2HTML Version 2002 (1.62) JA patch-1.4
by Kenshi Muto, Debian Project.
Original LaTeX2HTML Version 2002 (1.62)
by Nikos Drakos, Computer Based Learning Unit, University of Leeds.
Hope this helps,
Ross Moore
