Update of bug #47560 (project octave):
Open/Closed: Open => Closed
_______________________________________________________
Follow-up Comment #3:
The consensus, both from Octave and Matlab, is that many times there is no
need for sorting of the eigenvalues and they may be used as is. It is
incorrect, therefore, to penalize these applications by applying an additional
sort operation; Particularly because the eigenvector matrix would likewise
have to be sorted to match up to the new order of the eigenvalues and that is
harder than just sorting a column vector of eigenvalues.
There also exists an easy workaround, which is to call sort() yourself if you
need them in a particular order.
