copy¶
Copies a vector to another vector.
Description¶
The copy
routines copy one vector to another:
\[y \leftarrow x\]
where x
and y
are vectors of n
elements.
API¶
Syntax¶
namespace oneapi::mkl::blas::column_major {
void copy(sycl::queue &queue,
std::int64_t n,
sycl::buffer<T,1> &x,
std::int64_t incx,
sycl::buffer<T,1> &y,
std::int64_t incy)
}
namespace oneapi::mkl::blas::row_major {
void copy(sycl::queue &queue,
std::int64_t n,
sycl::buffer<T,1> &x,
std::int64_t incx,
sycl::buffer<T,1> &y,
std::int64_t incy)
}

Input Parameters¶
- exec_queue
The queue where the routine should be executed.
- n
Number of elements in vector
x
.- x
Buffer holding input vector x. The buffer must be of size at least
(1 + (n – 1)\*abs(incx))
. See Matrix Storage for more details.- incx
Stride of vector
x
.- incy
Stride of vector
y
.
Output Parameters¶
- y
Buffer holding the updated vector
y
