There is one prototype of ggbak
            available, please see below. 
ggbak( const char job, const Side side, const int_t ilo, const int_t ihi, const VectorLSCALE& lscale, const VectorRSCALE& rscale, MatrixV& v );
            ggbak (short for $FRIENDLY_NAME)
            provides a C++ interface to LAPACK routines SGGBAK, DGGBAK, CGGBAK, and
            ZGGBAK. ggbak forms the
            right or left eigenvectors of a complex generalized eigenvalue problem
            A*x = lambda*B*x, by backward transformation on the computed eigenvectors
            of the balanced pair of matrices output by ZGGBAL.
          
            The selection of the LAPACK routine is done during compile-time, and
            is determined by the type of values contained in type VectorLSCALE.
            The type of values is obtained through the value_type
            meta-function typename value_type<VectorLSCALE>::type. The dispatching table below illustrates
            to which specific routine the code path will be generated.
