clblasChpr
(order, uplo, N, alpha, X, offx, incx, AP, offa, commandQueues, eventWaitList)¶ wraps: clblasChpr
hermitian rank 1 operation with a general triangular packed-matrix and float-complex elements. hermitian rank 1 operation:
- ( A ← α X XH+ A )
Parameters: - order (clblasOrder [in]) – Row/column order.
- uplo (clblasUplo [in]) – The triangle in matrix being referenced.
- N (int [in]) – Number of columns in matrix A.
- alpha (float [in]) – The factor of matrix A (a scalar float value).
- X (pyopencl.Buffer [in]) – Buffer object storing vector X.
- offx (int [in]) – Offset in number of elements for the first element in vector X.
- incx (int [in]) – Increment for the elements of X. Must not be zero.
- AP (pyopencl.Buffer [out]) – Buffer object storing matrix AP.
- offa (int [in]) – Offset in number of elements for the first element in matrix AP.
- 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.
