There is one prototype of gehrd
            available, please see below. 
gehrd( const int_t ilo, const int_t ihi, MatrixA& a, VectorTAU& tau );
            gehrd (short for $FRIENDLY_NAME)
            provides a C++ interface to LAPACK routines SGEHRD, DGEHRD, CGEHRD, and
            ZGEHRD. gehrd reduces
            a complex general matrix A to upper Hessenberg form H by an unitary similarity
            transformation: Q' * A * Q = H .
          
            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.
