There are two prototypes of gees
            available, please see below. 
gees( const char jobvs, const char sort, external_fp select, MatrixA& a, int_t& sdim, VectorWR& wr, VectorWI& wi, MatrixVS& vs );
gees( const char jobvs, const char sort, external_fp select, MatrixA& a, int_t& sdim, VectorW& w, MatrixVS& vs );
            gees (short for $FRIENDLY_NAME)
            provides a C++ interface to LAPACK routines SGEES, DGEES, CGEES, and
            ZGEES. gees computes
            for an N-by-N complex nonsymmetric matrix A, the eigenvalues, the Schur
            form T, and, optionally, the matrix of Schur vectors Z. This gives the
            Schur factorization A = ZT(Z**H).
          
Optionally, it also orders the eigenvalues on the diagonal of the Schur form so that selected eigenvalues are at the top left. The leading columns of Z then form an orthonormal basis for the invariant subspace corresponding to the selected eigenvalues.
A complex matrix is in Schur form if it is upper triangular.
            The selection of the LAPACK routine is done during compile-time, and
            is determined by the type of values contained in type MatrixA.
            The type of values is obtained through the value_type
            meta-function typename value_type<MatrixA>::type. The dispatching table below illustrates
            to which specific routine the code path will be generated.
