copy
Copies a vector to another vector.
Description
The copy routines copy one vector to another. The operation is defined as:
where:
x and y are vectors of n elements
copy supports the following precisions:
T |
---|
float |
double |
std::complex<float> |
std::complex<double> |
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 vector x 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.
- 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.
