I'm using the package IEEEtrantools in an scrreprt document class environment. My problem is that, when using IEEEeqnarray together with hyperref, the link jumps to the beginning of the section and not to the referred equation. How can I make the link jumping to the equation?



\section{The equation}
    \frac{1}{v(E)}\frac{\partial}{\partial t}\Psi(\mathbf{r},\mathbf{\Omega},E,t)
  + \mathbf{\Omega} \cdot \nabla \Psi(\mathbf{r},\mathbf{\Omega},E,t)
  + \Sigma_t(\mathbf{r},E,t) \Psi(\mathbf{r},\mathbf{\Omega},E,t)
  = S(\mathbf{r},\mathbf{\Omega},E,t)
Referencing (\ref{eq:Boltzmann})...

Welcome to TeX.sx! A tip: If you indent lines by 4 spaces, they'll be marked as a code sample. You can also highlight the code and click the "code" button (with "{}" on it). –  Stephen Jan 17 '12 at 9:05

Just add a \phantomsection before \begin{IEEEeqnarray}{c}. While the appearance in print/pdf will be unchanged, hyperref will link/jump there instead of the (real) \section above.

Already seeing your next question "For each IEEEeqnarray?!", you could also use


after \usepackage{hyperref}. In that case you do not need to manually set the \phantomsections. (And you might want to send a bug report to the hyperref maintainer, Heiko Oberdiek, who generally is very helpful.)

As last remark: In principle the \phantomsection would belong directly before \label{eq:Boltzmann}. If you have an IEEEeqnarray with more than one \label inside, the hyperlinks would otherwise always aim at the beginning of the environment (instead of the line with the labelled equation). Therefore you could also instead declare (after \usepackage{hyperref})

\newcommand{\plabel}[1]{\phantomsection \label{#1}}

and use \plabel instead of \label inside the IEEEeqnarray environment.

Version 1.8 of IEEEtran.cls (and version 1.3 of IEEEtrantools.sty) now fixes the problem with hyperref under IEEEeqnarray. Enjoy!
