# Python version of the following original work:
# Title:	Sorting Real Schur Forms
# Author:	Jan Brandts
# E-Mail:	brandts-AT-science.uva.nl
# http://m2matlabdb.ma.tum.de/download.jsp?MC_ID=3&MP_ID=119
# http://dx.doi.org/10.1002/nla.274
# Institution:	University of Amsterdam
# Description:	In Matlab 6, there exists a command to generate a real Schur form, wheras another transforms a real
# Schur form into a complex one. There do not exist commands to prescribe the order in which the eigenvalues appear on
# the diagonal of the upper (quasi-) triangular factor T.
