copy (USM Version)¶
Copies a vector to another vector.
Description¶
The copy
routines copy one vector to another:
where x
and y
are vectors of n
elements.
API¶
Syntax¶
namespace oneapi::mkl::blas::column_major {
sycl::event copy(sycl::queue &queue,
std::int64_t n,
const T *x,
std::int64_t incx,
T *y,
std::int64_t incy,
const std::vector<sycl::event> &dependencies = {})
}
namespace oneapi::mkl::blas::row_major {
sycl::event copy(sycl::queue &queue,
std::int64_t n,
const T *x,
std::int64_t incx,
T *y,
std::int64_t incy,
const std::vector<sycl::event> &dependencies = {})
}

Input Parameters¶
- exec_queue
The queue where the routine should be executed.
- n
Number of elements in vector
x
.- x
Pointer to the input vector x. The array holding the vector
x
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
.- dependencies
List of events to wait for before starting computation, if any. If omitted, defaults to no dependencies.
Output Parameters¶
- y
Pointer to the updated vector
y
.
Return Values¶
Output event to wait on to ensure computation is complete.
