Function chpev_

Computes selected eigenvalues, and optionally, eigenvectors of a complex Hermitian matrix. Eigenvalues are computed by the dqds algorithm, and eigenvectors are computed from various "good" LDL^T representations (also known as Relatively Robust Representations). Computes all eigenvalues and, optionally, eigenvectors of a complex Hermitian matrix in packed storage.
