swap

Prototype

There is one prototype of swap available, please see below.

swap( VectorX& x, VectorY& y );

Description

swap (short for TODO) provides a C++ interface to BLAS routines SSWAP, DSWAP, CSWAP, and ZSWAP.

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 1.30. Dispatching of swap.

Value type of VectorX	BLAS routine	CBLAS routine	CUBLAS routine
`float`	SSWAP	cblas_sswap	cublasSswap
`double`	DSWAP	cblas_dswap	cublasDswap
`complex<float>`	CSWAP	cblas_cswap	cublasCswap
`complex<double>`	ZSWAP	cblas_zswap	Unavailable

The original routines SSWAP, DSWAP, CSWAP, and ZSWAP have five arguments, whereas swap requires two arguments.
