copy

Copies a vector to another vector.

copy supports the following precisions.

T

float

double

std::complex<float>

std::complex<double>

Description

The copy routines copy one vector to another:

y ←x

where x and y are vectors of n elements.

copy (Buffer Version)

Syntax

void onemkl::blas::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. The buffer 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.

Output Parameters

y

Buffer holding the updated vector y.

copy (USM Version)

Syntax

sycl::event onemkl::blas::copy(sycl::queue &queue, std::int64_t n, const T *x, std::int64_t incx, T *y, std::int64_t incy, const sycl::vector_class<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. 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.
