copy¶
Copies a vector to another vector.
copysupports 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 vectorxmust 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.
