?Thanks Sebastien!
I'll look at the codes in details, and if possible, I'll submit an API to dig out eigen info.
THX again~

Hi,For dimension 3, have a look in the file PCA_util.h for the
I went through the PCA package mannual and found that eigenvalues or
eigenvectors couldn’t be explicitly obtained. I didn’t find solution in
the part of linear algebra, too. Does CGAL 3.7 really not provide these
information by any means?
If there is something I miss which can easily help me compute
eigen-related info, could someone point out please?
If my guess is right about CGAL 3.7’s inability on this, then could
someone tell me why it is designed this way? Why eigen vectors and
values are hidden away? Do I need to do this myself?? This is so weird...
THX!!!

functions fitting_plane_3 and fitting_line_3. You should be able
to get both (see how these functions are called from
linear_least_squares_fitting_3 function).
Feel free to provide an API on how this could be exposed in CGAL.
