clblasDrot
(N, X, offx, incx, Y, offy, incy, C, S, commandQueues, eventWaitList)¶ wraps: clblasDrot
applies a plane rotation for double elements
Parameters: - N (int [in]) – Number of elements in vector X and Y.
- X (pyopencl.Buffer [out]) – Buffer object storing vector X.
- offx (int [in]) – Offset of first element of vector X in buffer object. Counted in elements.
- incx (int [in]) – Increment for the elements of X. Must not be zero.
- Y (pyopencl.Buffer [out]) – Buffer object storing the vector Y.
- offy (int [in]) – Offset of first element of vector Y in buffer object. Counted in elements.
- incy (int [in]) – Increment for the elements of Y. Must not be zero.
- C (float [in]) – C specifies the cosine, cos.
- S (float [in]) – S specifies the sine, sin.
- commandQueues (pyopencl.CommandQueue [in]) – OpenCL command queues. A list, tuple, or single instance of pyopencl.CommandQueue. Must not be None.
- eventWaitList (pyopencl.Event [in]) – Event wait list. A list, tuple, or single instance of pyopencl.Event. May be None.
Returns: A tuple of pyopencl.Event instances, one for each commandQueue supplied.
