EigenvalueSym

class EigenvalueSym extends Eigen with Error

This class is used to find the eigenvalues of an n by n symmetric matrix 'a' using an iterative technique, the Symmetric QR Algorithm.

Algorithm 8.3.3 in Matrix Computations. Caveats: (i) it will not handle eigenvalues that are complex numbers, (ii) it uses a simple shifting strategy that may slow convergence.
