Eigenvalues computation

[Daniel Tourde]

Hi !

I would like to trace the variation of the eigenvalues of a matrix D(k)
in function of k. Until now I have considered that Octave kept the same
order for my eigenvalues but in view of some strange results I have I'm
wondering if at a certain step of my computation the order does not
change (lambda8 <-> lambda9 for instance).

So, here is my question :
Does octave classify the eigenvalues of a matrix ?
If yes, how ?
If yes, how can I force Octave to keep this classification all along my
computation of lambda(k) x = D(k) x ?
If no, what can I do ? ....

Thanks for any answer. Best regards

                        Daniel Tourde
