copy (USM Version)¶
Copies a vector to another vector.
Syntax
namespace oneapi::mkl::vm {
event copy(
queue &exec_queue,
std::int64_t n,
const T *x,
std::int64_t incx, T *y,
std::int64_t incy,
const vector_class<event> &dependencies = {})
}

Description
The copy routines copy one vector to another:
y ←x
where x and y are vectors of n elements.
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 and Vector 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.
