copy
Prototype

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

copy( const VectorX& x, VectorY& y );

Description

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.

The original routines SCOPY, DCOPY, CCOPY, and ZCOPY have five arguments, whereas copy requires two arguments.
