EigenvalueSym

class EigenvalueSym extends Eigen with Error

The EigenvalueSym 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.
