There is one prototype of orgbr
            available, please see below. 
orgbr( const char vect, const int_t m, const int_t n, const int_t k, MatrixA& a, const VectorTAU& tau );
            orgbr (short for $FRIENDLY_NAME)
            provides a C++ interface to LAPACK routines SORGBR and DORGBR. orgbr generates one of the real orthogonal
            matrices Q or P*T determined by DGEBRD when reducing
            a real matrix A to bidiagonal form: A = Q * B * PT. Q and P*T are defined as products of elementary
            reflectors H(i) or G(i) respectively.
          
            If VECT = 'Q', A is assumed to have been an M-by-K matrix, and Q is of
            order M: if m >= k, Q = H(1) H(2) . . . H(k) and orgbr
            returns the first n columns of Q, where m >= n >= k; if m <
            k, Q = H(1) H(2) . . . H(m-1) and orgbr
            returns Q as an M-by-M matrix.
          
If VECT = 'P', A is assumed to have been a K-by-N matrix, and P*T is of order N: if k < n, PT = G(k) . . . G(2) G(1) and `orgbr` returns the first m rows of PT, where n >= m >= k; if k >= n, PT = G(n-1) . . . G(2) G(1) and `orgbr` returns P*T as an N-by-N matrix.
            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.
