I am using Eigen library with Eclipse C++. I wonder if there is a method or a function that I can use to reorder the Schur factorization X = U*T*U' produced by the RealSchur function and return the reordered Schur matrix TS and the cumulative orthogonal transformation US such that X = US*TS*US'

What I want is something similar to the MATLAB function "ordschur": http://de.mathworks.com/help/matlab/ref/ordschur.html

Many thanks in advance
