There is one prototype of her
            available, please see below. 
her( const Scalar >, const VectorX& x, MatrixA& a );
            her (short for hermitian
            rank-1 update) provides a C++ interface to BLAS routines SSYR, DSYR,
            CHER, and ZHER. her performs
            the hermitian rank 1 operation
          
A := alpha*x*conjg( x' ) + A,
where alpha is a real scalar, x is an n element vector and A is an n by n hermitian matrix.
            The selection of the BLAS routine is done during compile-time, and is
            determined by the type of values contained in type VectorX.
            The type of values is obtained through the value_type
            meta-function typename value_type<VectorX>::type. Table X below illustrates to
            which specific routine this dispatching will take place.
          
Table 1.48. Dispatching of her.
| Value type of VectorX | BLAS routine | CBLAS routine | CUBLAS routine | 
|---|---|---|---|
| 
                       | SSYR | cblas_ssyr | cublasSsyr | 
| 
                       | DSYR | cblas_dsyr | cublasDsyr | 
| 
                       | CHER | cblas_cher | cublasCher | 
| 
                       | ZHER | cblas_zher | Unavailable | 
            The original routines SSYR, DSYR, CHER, and ZHER have seven arguments,
            whereas her requires
            three arguments.
