The doc page discussing decompositions implemented in eigen (http://eigen.tuxfamily.org/dox/TopicLinearAlgebraDecompositions.html) isn't correctly rendering in either Chrome or Firefox. It's supposed to be a large table, but instead it's a large (and rather unreadable) list.
This should be fixed by commits:
