Hello everybody,
I want to ask something. Is it possible to compute eigenvalues of a real
general (nonsymmetric) matrix???
Thanx for help

Hi people,
I would like to ask all of you something.
I have a matrix function, which is given by
the modulus of the i-th eigenvalue of a real n*n matrix.
So finally I have a matrix, which has dimension n (n*1 vector).
Does anybody know how to compute the jacobian of such a matrix?
I need to compute the partial derivatives of the i-th modulus with
respect to the matrix.
Thanks for any ideas and help
