Re: [eigen] eigen expression template classes

[Christoph Hertzberg <chtz@xxxxxxxxxxxxxxxxxxxxxxxx>]

Hi!

You can get a bit more internal documentation, if you build the 
documentation yourself with EIGEN_INTERNAL_DOCUMENTATION activated:

$ cd path_of_build_dir
$ cmake -DEIGEN_INTERNAL_DOCUMENTATION=ON path_to_eigen
$ make doc -j8

This documentation is likely far from perfect (see also 
http://eigen.tuxfamily.org/bz/show_bug.cgi?id=138)

Also, there is some (old and at least partially outdated) documentation 
in the wiki, e.g.:
http://eigen.tuxfamily.org/index.php?title=Expression_templates
http://eigen.tuxfamily.org/index.php?title=Working_notes_-_Expression_evaluator

So in the end, you will need to look into the source and ask questions 
either here, on IRC or stackoverflow -- ideally also propose possible 
improvements (here or on http://eigen.tuxfamily.org/bz, or with 
Pull-requests).


Hope that helped a little,
Christoph

It would seem that this is possible if I understand the core types used to represent eigen expressions.  However, as far as I can tell, those types of not documented in the eigen documentation.  Nevertheless, it seems that there may be a (small?) set of those types.
