class Eigenvalue extends Eigen with Error
The Eigenvalue class is used to find the eigenvalues of an 'n' by 'n' matrix
'a' using an iterative technique that applies similarity transformations to
convert 'a' into an upper triangular matrix, so that the eigenvalues appear
along the diagonal. To improve performance, the 'a' matrix is first reduced
to Hessenburg form. During the iterative steps, a shifted 'QR' decomposition
is performed.
Caveats: (1) it will not handle eigenvalues that are complex numbers,
(2) it uses a simple shifting strategy that may slow convergence.
