There is one prototype of copy
            available, please see below. 
copy( const VectorX& x, VectorY& y );
            copy (short for TODO)
            provides a C++ interface to BLAS routines SCOPY, DCOPY, CCOPY, and ZCOPY.
          
            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 1.8. Dispatching of copy.
| Value type of VectorX | BLAS routine | CBLAS routine | CUBLAS routine | 
|---|---|---|---|
| 
                       | SCOPY | cblas_scopy | cublasScopy | 
| 
                       | DCOPY | cblas_dcopy | cublasDcopy | 
| 
                       | CCOPY | cblas_ccopy | cublasCcopy | 
| 
                       | ZCOPY | cblas_zcopy | Unavailable | 
            The original routines SCOPY, DCOPY, CCOPY, and ZCOPY have five arguments,
            whereas copy requires
            two arguments.
