Is there any built-in way in Eigen to re-orthogonalize matrix? When you multiply lots of rotations, matrix will eventually need to be re-orthogonalize. There are standard techniques such as using SVD and one can certainly spend a day writing and optimizing it by hand. However I'm hoping Eigen has few things built-in somewhere. There was a related question asked before but without clear answer in context of Eigen.
