Function: eiggn
Description: eiggn computes the eigenvalues and eigenvectors of a quadratic matrix (or array) in unsorted order.

Usage: y = eiggn (x {,xi})
Input:
x p x p matrix (real part of matrix)
xi p x p matrix (imaginary part of matrix)
Output:
y.values.re p x 1 vector with the real eigenvalues
y.values.im p x 1 vector with the imaginary eigenvalues
y.vectors.re p x p matrix with the real eigenvectors
y.vectors.im p x p matrix with the imaginary eigenvectors

Example:

x=#(1,3)~#(3,2)
eiggn(x)
