Copies a vector to another vector.
void copy(queue &exec_queue, std::int64_t n, buffer<T,1> &x, std::int64_t incx, buffer<T,1> &y, std::int64_t incy);
copy supports the following precisions and devices.
T | Devices Supported |
---|---|
float | Host, CPU, and GPU |
double | Host, CPU, and GPU |
std::complex<float> | Host, CPU, and GPU |
std::complex<double> | Host, CPU, and GPU |
The copy routines copy one vector to another:
y ←x
where x and y are vectors of n elements.
The queue where the routine should be executed.
Number of elements in vector 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.
Stride of vector x.
Stride of vector y.
Buffer holding the updated vector y.
