There is one prototype of ungrq
            available, please see below. 
ungrq( MatrixA& a, const VectorTAU& tau );
            ungrq (short for $FRIENDLY_NAME)
            provides a C++ interface to LAPACK routines SORGRQ, DORGRQ, CUNGRQ, and
            ZUNGRQ. ungrq generates
            an M-by-N complex matrix Q with orthonormal rows, which is defined as
            the last M rows of a product of K elementary reflectors of order N
          
Q = H(1)' H(2)' . . . H(k)'
as returned by ZGERQF.
            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.
