264. CBORIS: Eigenvalues and Eigenvectors of a Complex
Hermitean Matrix
by Egon Zakrajsek, University of Ljubljana, Ljubljana, Yugoslavia This subroutine can be used to compute all eigenvalues and corresponding eigenvectors of a generalized problem Ax = l Bx with A and B complex Hermitean and B positive definite. To use subroutines, matrices should be stored in a special way, see documentation, so that only N * (3N + 3) memory locations are used. These subroutines can also be used to compute eigenvalues and eigenvectors of a standard problem Ax = lx with A complex Hermitean. In this case, only N * (3N + 3) memory locations are used.
