Dear Marcelo,
A couple of suggestions, I find that forgotten math for me can be recalled by
calling up:

For specific derive related problems you might try to send a specific concern to
the attention of the authors:
The QR method for finding eigenvalues

Hessenberg Matrix
HESSENBERG(A)
This function converts any square matrix A into upper Hessenberg form. That is a
matrix which has zeros below the sub diagonal, but has the same eigenvalues as
A.

Subject: Problem with eigenvals
Dear Derivers,
I have some problems when using eigenvals.dfw which are shown in
the attached file. I hope somebody will tell me what I am doing wrong.
Thanks in advance,
Marcelo.
