There is one prototype of unghr
            available, please see below. 
unghr( const int_t n, const int_t ilo, const int_t ihi, MatrixA& a, const VectorTAU& tau );
            unghr (short for $FRIENDLY_NAME)
            provides a C++ interface to LAPACK routines SORGHR, DORGHR, CUNGHR, and
            ZUNGHR. unghr generates
            a complex unitary matrix Q which is defined as the product of IHI-ILO
            elementary reflectors of order N, as returned by ZGEHRD:
          
Q = H(ilo) H(ilo+1) . . . H(ihi-1).
            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.
