There is one prototype of hbgvx
            available, please see below. 
hbgvx( const char jobz, const char range, MatrixAB& ab, MatrixBB& bb, MatrixQ& q, const Scalar >, const Scalar >, const int_t il, const int_t iu, const Scalar >, int_t& m, VectorW& w, MatrixZ& z, VectorIFAIL& ifail );
            hbgvx (short for $FRIENDLY_NAME)
            provides a C++ interface to LAPACK routines SSBGVX, DSBGVX, CHBGVX, and
            ZHBGVX. hbgvx computes
            all the eigenvalues, and optionally, the eigenvectors of a complex generalized
            Hermitian-definite banded eigenproblem, of the form A*x=(lambda)*B*x.
            Here A and B are assumed to be Hermitian and banded, and B is also positive
            definite. Eigenvalues and eigenvectors can be selected by specifying
            either all eigenvalues, a range of values or a range of indices for the
            desired eigenvalues.
          
            The selection of the LAPACK routine is done during compile-time, and
            is determined by the type of values contained in type MatrixAB.
            The type of values is obtained through the value_type
            meta-function typename value_type<MatrixAB>::type. The dispatching table below illustrates
            to which specific routine the code path will be generated.
