Math & Science ⇒ \align counter not working

[J0mL-C]

Hello,
\align seems not functioning well:
it generates no numbering at all, and when referenced, shows the section number.

I tried to explain here. My class code is at last

Code: Select all

\begin{subequations} \label{e:015} %on page 16
	\begin{align}
		   & A\label{E-015-1}
          \intertext{procedemos a eliminar...}
	  U_1\cdot & A = B\label{E-015-2}
        \end{align}
some text....
\begin{align}
	U_2\cdot B &= 	L\label{E-015-3}
\end{align}
\end{subequations}

::: produces no numbers!:

A (expected I.1a)
procedemos a eliminar ...
U1 . A = B (expected I.1b)
some text...
U2 . B = L (expected I.1b)


But later

Code: Select all

\begin{subequations}
\begin{eqnarray}
	R&=S\label{E_m6000}\\
	&=S'\label{E_m6001}
\end{eqnarray}
\end{subequations}

produces

R = S (I.2a)
= S' (I.2b)

And later on
...some text... en la~\eqref{E_m6001} ... produces correctly ''en la (I.2b)''


BUT ....after some other text in the same subsection...

página~\pageref{e:015} \eqref{E-015-2} \eqref{E-m6001} \eqref{E-m6050}
just to prove the malfunction:
e:015 corresponds to the first ''subequations'' I put for you
E-015-2 is the second expresion in it
E-m6001 my (I.2b), I hope
E-m6050 the nearly next ''align'' expresion in a new paragraph

results in: página 16, (as espected) (I.1) (when expected I.2b again)!
(I.2.7.3) and (I.2.7.3) wich is the current ''\subsubsection'' number

It seems \align related counter doesn't counts, and \eqnarray one <<dies>> quickly...


I traied to use only eqnarrays instead of align, but getting another errors
I traied to use \usepackage{mathenv} deactivating amsthm, without success
The ams manual doesn't provide a clue for me, as it shows

Perhaps post a real compilable example, which we can test to verify and to fix the problem. I tried your code snippets, build an example with it, but it shows numbers! So the problem is hidden somewhere else.

Thanks, Stefan_K for you quickly (schnell) answer

This noon have I also trayed that way and also obtained your result.

But when all the chapters are "on", the problem arises,
I tried putting together all archives in a single one...(that is time consuming with latexstudio) with the same wrong behaviour.

When trying to avoid \align, with equation or eqnarray, the problem is another: for example: in section I-2.6.4., the numeration of formulae are (1-1a) and so; while later in section I-2.7.3. it returns to (I.0a).

Here is the first chapter and the corresponding source you

Das ist Modulo6.tex

Code: Select all

\documentclass[11pt]{book}
\usepackage[a4paper,twoside,margin=2.5cm,bindingoffset=1cm]{geometry}
\newcommand{\mititulo}{Espacios Vectoriales}
a lot, lot code

Wow, more than 1400 lines in the post, with the code. Did you try to make a smaller version to to reproduce the problem? Think of readers, and of the other people which google because of the same problem and arrive here.

I prefer firstly supporting you in making a good test case instead of fighting with huge amounts of code - and doing the same in the next case of a problem.

So let us know if something doesn't work in the process of making a minimal working example, see also minimalbeispiel.de for explanation about why and how.

Hello,
finally I could isolate the error. Time ago I did not know how suppress section numbering, and I added the command \nonumber after the section.

Here is the almost minimal code which causes the error. To remove it simply remove the ugly command

Code: Select all

\documentclass[11pt]{book}
\usepackage{amsmath}
\begin{document}
\frontmatter
\begin{titlepage}
  This is the titlepage
\end{titlepage}
\chapter*{Prologo}
  This is the prologue.
\section*{titleSec1}\nonumber
That is the error
\mainmatter
\chapter{First chapter}  
blah blah
\begin{align}
 here &= not\: numbered\label{E:001}
\end{align}

blah blah
\begin{align}
and &= not\: numbered\label{E:002}
\end{align}
Remove the \texttt{\textbackslash nonumber} command in line 10 to see \eqref{E:001} and \eqref{E:002} correctly
\end{document}

I'm sorry for the previous (long) post.
