There is one prototype of iamax
            available, please see below. 
iamax( const VectorX& x );
            iamax (short for TODO)
            provides a C++ interface to BLAS routines ISAMAX, IDAMAX, ICAMAX, and
            IZAMAX.
          
            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 1.14. Dispatching of iamax.
| Value type of VectorX | BLAS routine | CBLAS routine | CUBLAS routine | 
|---|---|---|---|
| 
                       | ISAMAX | cblas_isamax | cublasIsamax | 
| 
                       | IDAMAX | cblas_idamax | cublasIdamax | 
| 
                       | ICAMAX | cblas_icamax | cublasIcamax | 
| 
                       | IZAMAX | cblas_izamax | Unavailable | 
            The original routines ISAMAX, IDAMAX, ICAMAX, and IZAMAX have three arguments,
            whereas iamax requires
            one arguments.
