BibTeX

Here's a BibTeX entry for Eigen that you can use to cite Eigen in your academic publications:

 @MISC{eigenweb,
  author = {Ga\"{e}l Guennebaud and Beno\^{i}t Jacob and others},
  title = {Eigen v3},
  howpublished = {http://eigen.tuxfamily.org},
  year = {2010}
 }

If you are using the Natbib package, we recommend using \citet* and \citep* instead of \citet and \citep, as the latter commands tend to keep only the first-named author and "others".

The choice of the two main authors listed there is reasonable in general, but do feel free to use a different author field, for example if you think that in your particular case, you are relying on a feature developed by another author.
