There are two prototypes of larz
            available, please see below. 
larz( const Side side, const int_t l, const VectorV& v, const Scalar >, MatrixC& c );
larz( const Side side, const int_t l, const VectorV& v, const Scalar tau, MatrixC& c );
            larz (short for $FRIENDLY_NAME)
            provides a C++ interface to LAPACK routines SLARZ, DLARZ, CLARZ, and
            ZLARZ. larz applies a
            complex elementary reflector H to a complex M-by-N matrix C, from either
            the left or the right. H is represented in the form
          
H = I - tau * v * v'
where tau is a complex scalar and v is a complex vector.
If tau = 0, then H is taken to be the unit matrix.
To apply H' (the conjugate transpose of H), supply conjg(tau) instead tau.
H is a product of k elementary reflectors as returned by ZTZRZF.
            The selection of the LAPACK routine is done during compile-time, and
            is determined by the type of values contained in type VectorV.
            The type of values is obtained through the value_type
            meta-function typename value_type<VectorV>::type. The dispatching table below illustrates
            to which specific routine the code path will be generated.
