Hi,

I totally agree with Sameer here. Clearly Ceres is too sophisticated to be part of Eigen. Moreover, it's for double only, while we strive to stay as generic as possible.

No, Its not a good idea.Eigen is a linear algebra library (or atleast thats how most people think about it).why should a full fledged nonlinear least squares library be included in it?based on eigen is a very loose term. we use eigen extensively, but thats not the only thing we use.let me rephrase, Ceres is a large and complicated dependency.SameerOn Fri, Dec 7, 2012 at 1:57 PM, Thomas Capricelli <orzel@xxxxxxxxxxxxxxx> wrote:

definitely be a great option to move it to eigen, don't you think ? The

same for the other generic algorithm there might be there.
