Computes all the eigenvalues, and optionally, the eigenvectors of a complex generalized Hermitian-definite eigenproblem, of the form \( sub( A ) x=(\lambda) sub( B ) x, sub( A ) sub( B ) x=(\lambda) x, \mbox{ or } sub( B ) sub( A ) x=(\lambda) x \). Here sub(A) denoting A(IA:IA+N-1, JA:JA+N-1) is assumed to be Hermitian, and sub(B) denoting B(IB:IB+N-1, JB:JB+N-1) is assumed to be Hermitian positive definite. More...
