Description

The copy routines copy one vector to another:

y ←x

where x and y are vectors of n elements.

Input Parameters

exec_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.
