copy#
Copies a vector to another vector.
Description#
The copy routines copy one vector to another.
The operation is defined as:

copy (Buffer Version)#
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#
- queue
The queue where the routine should be executed.
- n
Number of elements in vector
x.- x
Buffer holding input vector
x. Size of the buffer must be 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 updated vector
y.
copy (USM Version)#
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#
- queue
The queue where the routine should be executed.
- n
Number of elements in vector
x.- x
Pointer to the input vector
x. Size of the array holding vectorxmust be 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 updated vector
y.
Return Values#
Output event to wait on to ensure computation is complete.
