There are two prototypes of hemm
            available, please see below. 
hemm( const Side side, const Scalar >, const MatrixA& a, const MatrixB& b, const Scalar >, MatrixC& c );
hemm( const Side side, const Scalar alpha, const MatrixA& a, const MatrixB& b, const Scalar beta, MatrixC& c );
            hemm (short for hermitian
            matrix-matrix operation) provides a C++ interface to BLAS routines SSYMM,
            DSYMM, CHEMM, and ZHEMM. hemm
            performs one of the matrix-matrix operations
          
C := alpha*A*B + beta*C,
or
C := alpha*B*A + beta*C,
where alpha and beta are scalars, A is an hermitian matrix and B and C are m by n matrices.
            The selection of the BLAS 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. Table X below illustrates to
            which specific routine this dispatching will take place.
          
Table 1.84. Dispatching of hemm.
| Value type of MatrixA | BLAS routine | CBLAS routine | CUBLAS routine | 
|---|---|---|---|

                       | SSYMM | cblas_ssymm | cublasSsymm | 
| 
                       | DSYMM | cblas_dsymm | cublasDsymm |

            The original routines SSYMM, DSYMM, CHEMM, and ZHEMM have twelve arguments,
            whereas hemm requires
            six arguments.
